The oceans are all already the world and the largest of all the ecosystems. Oceans are very large bodies of water that dominant the Earth's surface. The ocean is over with salt water all over and its region is like water world. The ocean is just like ponds and lakes, the ocean are separated into separate zones. First they have the: intertidal, pelagic, abyssal, and benthic. All of the four zones have much different kind of species. The ocean has many species even the land doesn't have. The intertidal zone is where the ocean meet the land.
The intertidal zone is where waves and tides come in and out. Because of the tides come in and out the communities are constantly changing. Also in the intertidal zone many people use this zone to have fun. People go surfing and people swim on water also people drive there boat around to have fun. Next we have the pelagic zone. The pelagic zone is much further from the land. The pelagic zone is cold but though is hard to give a general temperature, because that the pelagic zone is mixed with cold and warm water. The benthic zone of course is below the pelagic zone. But although the benthic zone is not the very deepest parts of the ocean. The bottom of the zone consists of sand, slit, and/ or dead organisms. The deepest and the last part of the ocean we have the abyssal zone. The water in this zone is extremely cold. The abyssal zone is around 3 c. it has highly pressured, high in oxygen content, but low in nutritional content. The abyssal zones is the mid-ocean ridges spreading zones between tectonic plates. The chemosynthetic bacteria thrive near these vents because of the large amounts of hydrogen sulfide and other minerals the emit. These bacteria are thus the start of the food web as invertebrates and fishes eat them.
The intertidal zone has not much species but the fauna include worms, clams, predatory crustaceans, crabs, and shorebirds. The pelagic zone has the species of is and some mammals. Which they are dolphins and whales for example. The benthic zone has all kind of bacteria like fungi, sponges, sea anemones, worms, sea stars, and fishes. The abyssal zone has many bacteria in it.
For example the shark, the shark is like the king of the ocean just like the lion the kind of the jungle. The sharks has many sharp teeth. When a sharks teeth is broken it can be replace really easily. The sharks is the top predator of the ocean, nothing in the ocean can really get the shark. A shark can ramp though bones easily so it is a very dangerous species.
The ocean takes 2/3 of the earth's surface and it still do now. It is amazing how deep the ocean can get and how cold it is. All kind of species were first came from the ocean.

The name of our biome is Deciduous Forest. The major Deciduous Forests are in the Northern Hemisphere and they are in North America, Europe, and Asia. The smaller ones are in the Southern Hemisphere.
Inside the Deciduous Forests they are many flowers, but they do not have much vegetation they have more trees then anything. They weather is mostly precipitation in the Deciduous Forests. The animals have to deal with the cold winters and the hot summers. Tress leaves fall off so the small animals don't have a place to hide themselves. Animals found in the Deciduous Forests found are Black bear, Brown Bear, Fox, Cardinals, Turkey, Scorpions, earthworms and many other animals and creature. They have Mushrooms which grows on the Forest floors. The kingdom Protista is Lichen which is half Protista and half fungi.
The average temperature of the Forest is 24°C and gets a high as 30°C depending on it's location. The average amount of rainfall is 76 to 152 cm per year.
The Deciduous Forest is one of the biggest forests in the world. The forest is basically a big green place that shelters animals and plants, and trees. It is always wet until the summer comes. The main tree there is the Maple Tree. The birds use the trees for their homes. The trees there grow thick bark so they can survive cold weathers. Other animals use the trees for shelter form the sun's heat. When people come to cut down the trees the take away the animals homes. The trees come crashing down and smashes the growing seeds and prevents them form growing. That could make the population of the plant eating animals decrease. The Forest grows mostly during the wet season.
Deciduous is very fertile soil land. The reason the deciduous soils so fertile is because it's enriched with leaf liter. Leaf liter is leaves, twigs, logs, and dead organisms that fall on the ground.
Insects, Spiders, Snails are common creatures that live in the Deciduous Forest, and many Cold-blooded vertebrates, such as snails, frogs, etc... are also common there. There many birds the like the woodpeckers, warbles, flycatcher, and many others. They live in the trees for homes and to hide for protection from predators. The bird predators are the Owl and the Hawk. Mammals in the forest consist of mice moles, bears, rabbits, and many other mammals. There are many carnivores in the forest. Living in nature is a major factor in whether an animal will survive or not. When the people cut down the trees they are destroying the animals shelters and food. It has even extended to even destroying a species.

The tundra is a treeless plain of the arctic and alpine regions. There are two different kinds of tundra biomes, and they are known as the arctic and alpine tundra. The arctic tundra is found at the top of the world around the north pole and the alpine tundra is found on top of cold and tall mountains. This biome covers a fifth of the earth's surface and can be found in places such as Canada, Greenland, Russia, Northern Europe, Siberia, the northern most part of North America and a few places in the Southern Hemisphere. It is dry and cold in the tundra biome, and the vegetation is little to none. Animals that can be found in the tundra are caribou, Grey wolves, arctic foxes, polar bears, golden eagles, musk oxen, Norway lemmings, red phalaropes, ruddy turnstones, and sled dogs. Plants that can be found there are lichens, dwarf willows, and cushion plants. The average annual temperature is -12°C to -6°C, and the average annual rainfall is less than 25 cm.
Temperatures during the arctic winter can be -51°C. The average temperature of the warmest month is between 10°C and 0°C. Sometimes as few as 55 days per year, they have a temperature higher than 0°C. The changes in rainfall is spread evenly during the year and is slight, varying from 20-30 cm.
The most typical animals found in the tundra are caribou, Grey wolf, arctic fox and polar bear. The caribou is a type of deer that varies in color. It has short hair with different colors that can either be almost black to brown, gray, and white. A caribou can be found at Scandinavia to Siberia, Alaska, Canada, and Greenland A caribou migrates many hundreds of miles in between their breeding places (hundreds of miles between their breeding ground on the tundra and winter feeding grounds found farther south). During breeding time, it produces one to two offspring.
Grass and other tundra plants are their main food in summer, but in winter it eats lichens. The Grey wolf is a canine carnivore that can be found in eastern Europe, eastern India, Russia, Canada and some of the northern United States. It lives in the high mountains of Mexico. In the tundra biome, a Grey wolf hunts and feeds on larger animals such as deer, caribou, and wild horses and they also feed on smaller animals such as mice, fish, and crabs. The Grey wolf produces 3-8 puppies in May or June. Another type of canine carnivore is the arctic fox. It can be found in the arctic regions of Europe, Asia, and North America. It hunts and feeds on birds, lemmings, marine life, and any other leftover animals found in the tundra. Every May or June, it produces offspring such as the Grey wolf does, and make 4 to 11 puppies. It has furred paws, small and round ears, and white fur. The polar bear is another typical animal found in the tundra, and is a carnivore. It can be found in Arctic Oceans to southern limits of ice floes. It hunts and eat seals, fish, seabirds, arctic hares, caribou and musk oxen. During summer, the polar bear eats fresh meat, berries, and leaves of tundra plants. In a day, it can eat 41kgs per food and will still feel hungry. It mates in midsummer and produces 1 to 4 offspring. The polar bear has white fur that helps them blend into the snow, and it can smell food even though if it is 32km away.
In tundra soil, permafrost a permanently frozen layer of ground 609cm thick, is found. Tundra plants and microorganisms grow in the permafrost. The most typical plants found in the tundra are lichen, dwarf willow, and cushion plants and they can be found in the tundra. Lichen are plants that grow on the exposed surfaces of rocks. It is made of fungus and algae living and growing together. Dwarf willow are small shrubs that grow in the tundra. Cushion plants grow in a low, tight clump and looks like a little cushion to protect them from the cold. Plants in the tundra biome have many adaptations. During cold and harsh temperatures, they can be small and grow close to the ground. They even take in more heat from the sunshine than they get from other plants.
For most of the year, the tundra biome is covered in snow. During short summers, ice and snow melt to leave pools of melted water. Permafrost is frozen ail year long. If single species get eliminated or if permafrost gets disrupted, the tundra biome may get severely damaged.
In conclusion, the tundra is the coldest and driest place on earth. Animals in this biome are adapted to handle cold winters and breed and raise offspring quickly in the short and cool summers. Since annual precipitation is really low, less than 10 inches, water is unavailable during most of the year. Also, since there is so many plants in the tundra biome, animals get more food. Most animals found there are vegetarians, so animals will not have any problems finding food in the tundra biome.

The biome is call the ocean, to be specific they are call the marine. An ocean is a large body of salt water that covers 70°C of the whole earth. Ocean can be find in a lot of place because it is everywhere. Some examples are the Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean, and the Antarctic Ocean. All five oceans got their own differences. The Arctic Ocean is very near the North Pole; it is the smallest out of the 5 oceans in the whole world. The area is 14 million km. In the water, they are mostly sand, gravel, oil and gas field, iceberg, and glaciers. Antarctic Ocean is the second to the smallest. It is on the opposite side on the world which means they are near the South Pole. The Antarctic is the neighbor of Pacific Ocean and Atlantic Ocean. Antarctic has different water than them, so that is what makes them not mix together. Indian Ocean is the third largest ocean of the whole world; it also covers 20%of the earth's surface. It is located by Southern Asia west and Arabia Peninsula and Africa. The totally area is 73,556,000 sq. km. It has a Monsoon Wind System, the wind affect the ocean's movement a lot. The Atlantic Ocean is the second largest ocean in the world. It covers 20%of the earth's surface. The w hole Atlantic, includes two parts, it is the South acid North Atlantic Ocean, and they are separate by the equator. It is located from North and South America to Asia and Africa. So the. shape of t he ocean is like an S. The totally area of tile ocean is 106,450,000 sq. km. Last, is the Pacific Ocean. It is the largest ocean from all the five oceans. It is located Southern Asia, Australia and the Western Hemisphere. It has an area of 156 million sq. km. It is 15 times the size of the US, actually bigger than all the land combined. In the water, they have gas and oil field, sand, gravel, arid fishes. This ocean is very dangerous because volcanoes surround it, earthquakes, typhoons, hurricanes happens all the time, and a lot of pollution. Animals that live in the ocean are mostly fishes, and other sea animals. The annual rainfall of the ocean is 3.9 cm per year. The ocean is very important, because of the water and because it is the habitats for a lot of different animals and plants.
Different oceans have different environment because they are located in different part of the world. Different part of the world have different tiling happening so it affect its environment. Like I explained in the first paragraph, in the water they are mostly sand, gravel, and animals. Now we got more polluted ocean than we use to have, because people pollute the oceans more and inane some sea animals suffer. One thing is so good and special about our bionic it is the way the water cycle work. All water cycles start from an ocean, because evaporation. The suit evaporates from the ocean, or any other large body of water. That is a very important function because of the water cycle we create rain. Rains are a very important element in some really dry biomes, like the desert. The unique part about that is that we do not need water then. That is because we are already a big body of water. That make rainfall is not very important to the oceans. Water qualities depend on which ocean. However, to wrap it up, the qualities of water are mostly polluted, so you would never want to drink water that is Straight from the ocean, rainwater is the freshet so before the rain hit the ocean it is still fresh. Last but not least, one more special thing we have is out minerals. We have special salt and carbon dioxide. The carbon dioxide and salt are very important to the ocean. The salt in the water is very special, it is only found in the ocean. The carbon dioxide make this kind of cycle that make the pH level in the water balance, that way the animals in the water can survive.
Algae are examples of plant that is found on the ocean. Different algae have different colors. They have different color because different colors mean different types. They are marine plants and they are not microscopic so you do not need a microscope to look at it. The kelp is the biggest algae, they wan be 2.54 m long. They are brown in color. Algae are found in almost everywhere; they are found in the water level that you can still see the sunshine. That is because of all the photosynthesis, algae do also. Animals that are found in our biome are all the sea animals. Examples are like emperor angelfish and killer whales. Emperor angelfishes are very colorful, that's because they change color while they grow. There are tropical marine fishes. They are found in the Indian oceans, the Southern Pacific Ocean, and the Caribbean. They are mostly feed on smallest animals in the water, so they are the secondary predator. In addition, they live in reef's line a lot of other marine life too. Killer whales are the largest in vie whale family. The male can grow up to 7.0m, while the female can grow up to 6.4m. They are all black, white, and gray in color. They are mostly found in cold water, place near the polar region. They car, also be Bound in Western Mediterranean, Arabian Sea, and the Gulf of Aden. They like the deeper water so sometime they can stay down there for 5-15 minutes. however, it is very rarefy for them to Stay underwater for more than 5 minutes. Do not let their name make them have bad reputation; they are called the Miler whales, but they never killed in the wild before. They only feed on animals that are smaller than them, sea lion is one the things they eat they are also secondary predators.
As you can see, the oceans have some very unique characteristics that you cannot find in other biome. Therefore, the ocean is very important to us, not only because of evaporation but also all the sea life. Some marine lives are facing extinction, which is because we are harming them. Not only by polluting but also by not showing that you care. If we continue to pollute the ocean and not showing care, a lot of marine will extinct not long after. By then we cannot look at some really unique animals that is only found in our biome, that is going to be really sad to some people who precious these animals. Love and save your environment by doing your part, if everybody starts acting that way we would never worry about extinction again. One word to always keep in mind is that we have to think about the root of everything. If no water equal no rain, if no rain the agriculture business would fall apart. You will just have to keep in mind that you should precious everything that you have, before you cannot see it no more. Next time if you see a big blue body of water, breathe deep sand feel what is it like to be in the nature.

The desert biome is mostly located in northern Africa, western North America, western Asia, the center of Australia, and on the west coast of South America. It is the hottest biome on earth and is known of the land of extremes. It can be extremely hot and extremely cold. The plants and animals found in the desert are ones that are very adapted to the environment of course.
The desert can be over 38°C during the day but below 0°C at night. This is because the desert is bare. There is little protection to keep them from heating up in the sun and cooling off when the sun disappears at night. The amount of rainfall also varies. Deserts only receive less then 25cm of rain each year. Even though there is little rain in the desert, when it does, it pours. It can cause flashfloods in the desert. After a storm, it might not rain for weeks or months. Deserts receive the least rain in spring and summer. In December to March is the time period when the desert receives the most precipitation. In May and June it doesn't receive any at all. The temperatures in the desert get so hot that they cause you to hallucinate. During the winter the temperatures are lower than usual, in spring and summer it gets hotter, and in the fall it cools down a little bit.
In the desert you would find many plants. They also have to adjust to very hot days and very cold nights. Some plants have very long roots that grow in to the ground to reach underground water sources. Some even suck up as much water as they can when it rains and they save it in their stems and leaves. Rain also brings life to the desert. After a big storm, billion of seeds get buried and they come to life, but after only about 8 weeks, the flowers would be gone. The most common desert plant is the cactus. Some other desert plants are the saguaro. The stem of the Saguaro Cactus stores all of its water. Other plants in the desert are barrel cactuses, dragon tree, octillo tree, boojum, yucca, and the agave plant.
There are hundreds of different animals that live in the desert. Most of them can only be found at dawn or dusk because that is when they move around. Animals in the desert eat plants and each other to survive. Many feed on the roots, stems, leaves, and seeds of plants. Bigger animals then eat these animals. The desert jackrabbit eats on cactus. Camels are the most well known desert animal. Other desert animals include addax, armadillo lizard, cactus wren, chuckwalla, dingo, great mouse tail bat, lappet-faced vulture, northern grasshopper mouse, sidewinder, and western blind snake.
The desert is unique in many ways. It is also very different from every other biome. Some deserts are even cold. It's called the Gobi Desert in Asia. There are even some types of desert. One called rain shadow deserts. Mountains on the edge of deserts prevent rain from entering. The rain stays on the other side of the mountain creating rain forests next to many deserts. Deserts are second only to tropical rain forests in the variety of plants and animals that live there. So as you can see, this biome is very unique in its own way and that is what is so great about it.

Normally found in Brazil, Asian, and south Africa is the Tropical Rainforest. It occurs near the equator with a latitude of 23.5 degrees North. They have a high primary productivity, even though they exist mainly on quite infertile soils. In a tropical rainforest the temperature ranges from 20-25°C but it varies through out the year. The rainfall is very high with heat that is constant. It's generally 200-450 cm per year.
There's over 100 different trees, that are 23-25m tall. There are very short dry periods through out the year. Being only 12 hours of sunlight daily less than 2% reaches the ground. There are 3 layers which are canopy, the understory, and the ground layer. Most of the nutrients are held in the plants themselves and are rapidly recycled when the plants die or when parts such as leaves fall off and decompose. A lot of the roots from the tall trees spread 1 or 2cm of the soil and take the nutrients from decomposing leaves and other plant parts.
The one day Orchid, it only blooms for one day. It is found on the forest floor and uses trees and tall plants for support. It is one of the most interesting and rarest plant found in an tropical rainforest. Threes other plants such as the non native plants and exotic plants. Tropical rainforest contain more than half of the worlds species of living things. Like forest carnivores, deer, bird of prays such as eagles, hawks, owls, bats, marmosets, and bromeliads vines. The Peru or Brazil tropical rainforest may hold 1,200 or more species of butterflies, twice the total of the US. There are many undiscovered species being destroyed many may be possible cures for cancer and AIDS.
The tropical rainforest is the one of the richest biomes in terms of number of species. Rainforest are disappearing at about 0.3km2 per minute day and night. As the population of the earth grows the more we need rainforests. If it continues major climatic changes will occur. The tropical rainforest once covered more than 16% of the earth's total land surface but now they cover less than 6%.

Our biome is on grassland and the terrain is mostly covered with grass. Grassland are found throughout the world except Antarctica. Sometimes grasslands are called prairies, Savannah, or steppes. These grasslands are usually found between the desert and the forest. There are three different types of grasslands such as Tall grasslands could grow as high as 2m. The mixed grassland could grow as high as 0.6-0.9m. That last type of grassland which is short grassland are desert like because its plants are short. Grasslands summer temperature is 38°C and during winter season it is -40°C.
Grassland land environment is difficult for plants to survive because 25-76cm of rain per year isn't a lot. There isn't much trees in grasslands because there is too much rain and not too much water. Grasslands have high organic content and concentration of calcium carbonate in the B horizon which typifies the dark brown most soils developed under the grassland temperature. It also has the world's most fertile soils like the Chernozems. The Chernozem is usually in eastern prairies of the US, the pampas of South America, and the steppes of Ukraine and Russia.
One quarter of the Earth's land are Grassland. The typical plants in grasslands are Prairie blazing star. The Blazing star is one of the most beautiful flowers on the tall grass prairie and could grow as high as 9m. The blazing star's color is magenta and many types of butterflies are attracted to it. Another type of flower found in grasslands is the Sweet cone flower. The cone flower could grow as high as 1.8m if it is planted in moist soil. The animals found in grasslands are the Warthog, Black Rhinoceros, and the brown hyena. Warthogs survive by eating small mammals and eats carrion. The black Rhinoceros survive by eating leaves, buds, and small trees or bushes. The brown hyena survive by staying near the coast line and prey on dead whales and seals.
Therefore grasslands are good a habit for these animals and they could survive well with only 25-76 cm of rain a year. Some of these animals could prey on other animals easy because of the high grass that cover them. There is good soil to produce plants for the animals to eat and it continues the cycle of grassland life.

Just think it's an excruciatingly hot day and you badly need somewhere to cool off. The you would want to come down to our biome. Our biome is called a Tundra. It's very cold with temperatures from 10°C to -12°C basically it's the same temperature all year round. You can find most of these places in Northern Canada, Russia, and Alaska (The United States). From the moment that you step onto the Tundra all you can see in white snow and ice or frozen brownish water. The ground is frozen year-round, known as permafrost. Tundra is a polar desert with low rainfall and precipitation. The rainfall is scarce; it only rains 25cm a year. The plants grow in the North of the arctic tundra. The winters are long and cold, and there is a short growing season, of less than 60 days. There is an annual 0 to 24 hour change in day length. There is constant darkness in the winter, and constant sunlight during the summer.
If you're a hunter then I don't think that you'll want to come to our Tundra's because hunting and pouching is illegal. But for the others that like animals or like to observe them we have many different types. Such as Arctic Fox, Polar Bear, Golden Eagle, Red Phalarope, and for you invertebrate lovers we have worms and crabs which come to our Tundra's during migration. Most of the animals are carnivores which eats smaller animals and hunt for their food while others eat plants and seed that grow around the tundra. We also have many endangered species. For instance the Chinook salmon, Green Sea Turtle, Curlew Eskimo, American Peregrine Falcon, and the Northern Sperm Whale just to name a few. We also have many plants such as lichen, dark red leaves, cotton grass, cushion plants, and many different types of seeds. The plants that grow there are shrubby or mat-like vegetation. This area encircles the North Pole and extends to the taiga to the south.

Our Biome is on a Tropical Rain Forest. Most Tropical rain forest is located in tropical parts of the world. Meaning places that are hot and humid are most likely to be a tropical rain forest. All across the world tropical rain forests are located in Asia, Africa and South America. A lot of the things found in the tropical rain forest are in America. Such as fruits and animals. Parrots are one type of bird that most Americans own in the United States today. One way of noticing a tropical rain forest is that all tropical rain forests are located in places which are hot and humid. That's because the sun shines there a lot, and the weather feels real warm. Ways you can research a tropical rain forest is searching the web for information, and pictures in which how a tropical rain forest looks.
A Tropical Rain forest looks very colorful. Most things that live in the rain forest are all camouflage. Like for frogs, they might look the same as a tree. Most living creatures are to be camouflage so that nothing will bother them. Some plants in the tropical rain forest have spikes that stick out. The spike on the plants can poke out and poison you if the plant is a poisonous plant. Some organism in the rain forest is organisms such as Chimpanzees, snakes, bird and etc. The rain forest has a big mammal population meaning there is a big amount of species of different types of living organism. The tropical rain forest is a very big place. When you visit a tropical rain forest your goal is to be very careful. You may never know what pops out; it can be a snake animal or even bugs. What are scary about a tropical rain forest are the birds. There are a lot of birds in the Rain forest that can either is up to 61cm long or even bigger.
The annual rainfall of a tropical rain forest is one point five to ten meters of rain. In that case there can be some major floods in certain parts of the tropical rain forest. In Africa the annual rainfall of a tropical rain forest there is about 178cm of rain. The temperature there is about 26.7°C; One flood can cause a major casualty for a species that live in the tropical rain forest. Ten meters of rainfall is a lot of water. If like it rains ten meters of water in a 0.8km2 spot. That can be like a lake if the water is stored there without being evaporated. The way I would describe a tropical rain forest is that it's very bright and colorful. There are a lot of different types of plants in the tropical rain forest. Such as many different types of roses and violets. Vegetation grows in the rain forest also. Some vegetation is eggplants, turnip, David Sonia and Alloxyton flamigeux. The environment of a Tropical Rain forest is that it's a place that really looks beautiful, but everything is like all messy in a good way. The trees are all very tall and some of the dirt on the ground is all muddy and dirty.
The water cycle in the Tropical Rain forest is that the water comes from the heavy rain during the year. Then the water falls into a spot where lots of water is located. At the spot where the water is stored that's where all the animals and creatures go to get a drink of water. The water forms what is called a pond. The sun then evaporates the water, which repeats its cycle all over again. Most rainfall comes during the spring and winter of the year. During the summer, and fall the weather is just hot as a frying pan. Most creatures go in search of a place too cool off. If a animal can't find a place too cool off they mite go and find something good to eat which is fruity, and can get their minds off of things. From my own sources I think that the soil in the rain forest must contain a lot of minerals because a lot of things have died in the rain forest. A rain forest is mostly located near an ocean. Lots of water comes from the ocean that waters the plants. The plants are water by a process. First the water goes onto the soil. The soil then saturates the water bring it to a plant that is in need of water. Some certain nutrients found in the in the soil are leftovers from a dead bug.
Some plants that I can name in the rain forest are David Sonia, Syzyglum, Luehmannii and Elaeocarpus ticulatus. These plants are located in spots that are wet and humid. These certain plants survive by the way they grow. Some of the plants form a camouflage. A camouflage is that a living thing shade matches their own surroundings. Another way a plant can survive is by have a hard protection. Like Durian, durian has a hard shell to protect itself from animals trying to eat them. A durian ion a tropical fruit that some people like to eat. The Durian tastes good but its smell is not polite.
Some animals in the rain forest are Chimpanzees. A Chimp can survive itself because their brains are very intelligent. A gorilla is not as intelligent as a Chimpanzee but a Gorilla has a lot of muscle. A bearded pig that lives in the rain forest looks very funny. It's fat, and hairy. The bearded Pig eats hay and certain creatures, which live in the Tropical rain forest. The Bearded Pig lives in a spot that is all muddy. Where lots of bugs fly around. You can consider that a bearded pig is very dirty, and that no one wants to eat it. Like if a jaguar was hungry I don't think that the jaguar would eat a dirty pig. The way the Bearded Pig might smell is very musty since the pig rolls in the mud, and its sweaty sweat.
As your journey comes to a halt. You should be getting a picture in your mind of a Tropical rain forest. As you can see that the tropical rain forest is home too many types of species, plants and food. The weather there is pretty mild, and humid. There are over two tropical rain forests on earth. Tropical rain forest is located at the southern parts of different continents. There are 3 known places, which a Tropical rain forest is located. One in Asia one in Africa and one in South America. The number one predator in the tropical rain forest to watch for is a snake. Snakes roam around the forest in seeks for things to bite. The Cobra will poison you with its venom if one bites you. Cobras and other types of snakes claim the forest besides other animals. Tropical Rain forest is a place to visit if you are a person that loves nature. Many environmentalists today are trying their best to keep the rain forest clean. What that means is to not cut down trees or hunt for animals that are becoming an endanger species.

Peter Yee, Robert Tang, Jeffrey Chen, Li, Li Fu, and I Reggie Moore are members of the TRFIC our mission is to inform you the scientific information on the world's Tropical Rain Forest that we've just researched. In this presentation you will have gained knowledge not just on our Biome but other thing's for example the animals that live in Tropical Rain Forest, the environment, its temperature and the location just to name a few. We the group members have been asked to come together and work as a cohesive unit and also to teach you the facts about this particular Biome. One other thing just so you know all the information that we present to you has taken years to find out about the Tropical Rain Forest we are the first to deliver the information to you NASA's data has nothing on us were are the best at what we do. The
Tropical Rain Forest is possibly the most diverse Biome in the world. Tropical Rain Forests can be found in Brazil, Southeast Asia, Pacific Island and West Africa. The average temperature ranges from 25 to 35°C. The average rainfall is about 250cm annually each year. Some typical animals that are found in this Biome are Toucan Sam, Jaguars, Chimpanzee's, Parrots, Gorillas and last but not least everybody favorite animal Tarantula's. The Tropical Rain Forest is home to some of the smallest to largest animals in the world they all are dangerous, beautiful, and even the strangest looking ones. Some plants that can be found just to name a few athrium, caladium, philodendron and garden callas.
The name "Tropical Rain Forest" came from the forest specific location. It can be found in Latin America one third of the world's Tropical Rain Forest are also in Brazil. Three others are located in Southeast Asia also Pacific Islands and West Africa. The average temperature rises from 25 to 35°C the average rainfall 250cm of rain annually each year. But the largest temperature Rainforest are found on the Pacific Coast. Some smaller Rainforest can be found on the Southeast Coast of Chile in South America. Some typical animals that are found in this Biome are Ramphastos Sulfuratis ( Toucan Sam) and Fulgora Laternaria ( Peanut Head Bug). Because of high rainfall the plants growths is very robust its just mainly the cycle its regrowth of leaves occur through out every year. Most of the animals that were named live in different types of the Rain Forest. Some key features are to watch out for the spectacular art work and the given information that the Tropical Rain Forest Information Center offers.

All along the western coast of North America, stretching from just South of Anchorage, Alaska, to the northern part of California is an ecosystem that scientist are only now starting to fully explore. It is often called the Temperate Rain Forest. It is the temperate rain Forest. It is an area where land and sea meets. There are glaciers covered peaks and deep ocean water.
On the west coast the people have found the region where there are mild winters and summers. Summer temperate rarely exceed 30°C and winter seldom goes below 0°C. There are occasional blasts of cold arctic air that will send temperatures drooping and cause snow to fall even on coastal beaches, and such weather is rare. There is a lot of rain that falls here. In the heaviest months, From October to April, there is often three to four storms a week. Many weather stations record over 15cm of precipitation per month during this period. This rain fall is known as orographic rainfall. The precipitation exceeds 400cm and some times 30cm per year in the interior.
The Pacific Old Growth Forest isn't well known. There are only four species of trees are common and there are only several thousand species of insects. There are also browser. Browser is a animal that eats tree leaves, twigs and branches.

Can you imagine yourself living in a place, where it's always hot, humid, and little water? The desert is the hottest biome on Earth. An area where there's less than an average of 100mm of rainfall is considered a desert. Most deserts lie in between the Tropic of Cancer and Tropic of Capricorn. Deserts can be found on 5 of the 7 continents: North America, South America, Africa, Asia and Australia. The average annual rainfall is less than 25cm per year. Deserts can get extremely hot. The air can be up to 40-50°C, the sand is 75°C and the land can range from 51.67-56.67OC. As you probably already know, deserts are known for its cactuses and reptiles. As you read along, you will learn more about the different kinds of plant and animal life of deserts.
When you think of deserts, you think hot and dry, right? Those two things are exactly what a desert is. The reason that it's always so hot is because there's little rainfall. The desert is known as a land of extreme because during the day, the temperature can be well over 38°C and during the night, it can be below 0°C, which is freezing point. That is because deserts are bare and they don't have anything to keep the desert cool as well as keep it warm. The seasons are usually warm throughout the year and extremely hot during the summer. Winter is when there's little rainfall. The rainfall is usually low and when it does rain, lots of rain pours down at once. It can cause floods by the rainstorms, and after that, the desert may not see any more rain for the next couple of weeks or months. Those couple of days or weeks is the only time where the desert will receive all of the year's rainfall. So all of the plants and animals will only receive rain then, and that's it for the year. The water cycle kind of fits into a desert but not quite. First it rains, but the rain can evaporate before it hits the ground. The plants collect the water that does fall to the ground. Plants can lose the water that they've collected and evaporate into the air. Since there isn't any area of water, the precipitation has nowhere to go except for the plants. Then the whole cycle begins again. So basically, the water cycle of a desert contains rain, plants, and evaporation
Since deserts are hot and dry, would you expect to find any life there? Despite the climate, there is some plant life. In fact, it was estimated that there are about 1,200 species of plant to be found in the Sahara. The main source of food for plants is water so it's a real challenge since water is so scarce. Desert floras have adapted to the environment by avoiding the low rainfall or take in the water. The storm can kill the plant or it may drown it. Ephemeral, also known as annual plants survive in periods where there's little water because their seeds sprout only after heavy rain. They will grow rapidly and live their whole life cycle in just a few days. Can you believe that grasses grow in a desert too? They can store a large amount of water in its roots for later sprouting. The top of the plant, where it's above the surface, will eventually die but thanks to its roots, it can grow again. The roots will not die if the top portion does. Geophytes remain underground most of the time, as bulbs. They wait for rain to come and when it does, it quickly produces stems and flowers. Succulents, like the grass I mentioned take in large amounts of water and stores it for droughts. They have a really low surface area and it causes the plant to lose water because of evaporation. They use photosynthesis to convert carbon dioxide into organic compounds by using energy from the sunlight, like most plants. The best known succulents are cacti. A kind of cacti is the saguaro, which can grow up to 15 meters over the years. There are also shrubs and small trees in a desert. The leaves are usually shed during the hottest season of the year. Their roots try and search for water beneath the surface so it can be as deep as 50 meters under the ground. There is this one tree named the Joshua Tree which is in the Mojave Desert which has spiky leaves and fruit which some animals eat. Some have short thick trunks that are used to pick up water when it rains. Most plants in the desert look very much different from what we've seen. They grow spikes or thorns to protect themselves from being eaten by other animals.
The animals living in a desert need to adapt to the climate in order for them to survive. The obstacles that they go through are the extreme temperatures, lack of food and shortage of water. However, all sorts of animals can be found in a desert. They usually try and hide behind rocks to avoid the sunlight or bury themselves in the sand. There aren't much large animals that live in the desert due to the heat and not able to store water in their bodies. There's even been fish found. Mammals living in the desert are able maintain a constant body temperature despite of the weather. When they get hot, they sweat and it comes onto their skin which then evaporates and that keeps them cool. The mammals that live there are usually small like the kangaroo rat because there isn't enough food for large animals to feed off of. These mammals include insect-eaters like hedgehogs and carnivores such as foxes, cats, and weasels. However there are large animals like the camel, gazelles and antelopes. They have found their own way of surviving. Camels can drink up to 25% of their body weight with water. They can store large amounts so they can use it when there isn't any water. They also store large reserves of fat in their humps and use that as food when there isn't any. Insects found in deserts are members of a group of organisms known as arthropods. It contains arachnids, which are scorpions, spiders, solifugids, mites and ticks, crustaceans, which are crabs, lobsters and woodlice, and myriapods, which are centipedes and millipedes. Arachnids have a hard waxy outer layer, which is waterproof so they don't lose water due to evaporation. The crustaceans and myriapods often hide in the sand to avoid the heat and sunlight. There are also flying insects like locusts. They fly across the desert to find food and water and sometimes travel in a large pact covering as much as 1,000 square kilometers, and can destroy crops at an alarming rate. Other flying insects are flies, wasps, butterflies and moths. Insects that don't fly include earwigs, termites, ants and beetles. Scarab beetles eat the dung of desert animals such as camels and goats, which they roll into balls and bury in the ground. The predatory carabid beetle hides from the sun while at night it comes out and hunts. Scorpions are probably the best adapted animals in a desert. They lose water very slowly, and nearly all of them spend their days in burrows or under rocks. Scorpions have pincers, which are used to hold their prey while they shoot them a deadly poison from the sting in their tail. They mostly eat insects and spiders, but sometimes will kill other scorpions. All of these insects I mentioned are invertebrates, which means they don't have a backbone. The creatures that do have a backbone are called reptiles and they're cold-blooded. This means that their own body cannot keep them warm so they rely on the environment The sun can sometimes be too much for them so they move from shadow to shadow. Reptiles have thick skin and don't lose a lot of water. Most of them usually hunt or is active at night because they are cold blooded and there isn't any sun for them to keep their bodies warm so they don't have much energy. The main and most common reptiles found in deserts are lizards, snakes and tortoises. Lizards and snakes are carnivorous, but tortoises are herbivores. The smaller lizards get their food and fluids from insects while snakes and larger lizards eat small mammals, eggs and other lizards. The last group of animals is birds. They have 2 great advantages: one, they can fly great distances in search of food and water and two, their flight generates a lot of heat. Birds are naturally adapted to high body temperatures and their feathers help them in the process from the heat of the sun. Since there aren't many trees or bushes in a desert, these birds have to adapt to a life on the ground. Many of them are much smaller than places in other regions. They mostly eat insects, while others survive on seeds and some even eat small mammals. As you can see, there are a variety of animals that call a desert home.
Deserts seem like an interesting place to live but a real challenge. You have to adapt to this and that since the climate is so different than what we are used to. Only certain living things are able to survive in this type of environment. I think it would be hard for human beings to actually live in the desert since our bodies can only take in a certain amount of heat and we always need water to survive. I've always known that cactuses lived there, but there were many more different kinds of plant as well as animals. The insects and reptiles seemed to fit into this environment but I can't imagine so many plants living there. Now I can see why deserts are such a unique place, with such an extreme climate and all the different life out there. I would want to go and visit a desert but only for a couple of hours and if I have lots of bottles of ice cold water on me. In conclusion, deserts are definitely the neatest and hottest biome on earth!

Savanna is a biome that I am going to write about. It is easy to be found in Africa, Australia, and Indian.
A savanna is a rolling grassland, dotted with trees. It can be found between a tropical rainforest and desert biome. Burning the forest and felling the tree create savanna. Large animals also can turn a forest to a savanna. Savanna has hot and dry climates. Temperatures range from 17.9 to 22.4°C. Annual rainfall depends on the geographic location. Some savannas get as little as 25cm of rainfall per year and some can get as much as 127cm per year. Not enough rain falls on savanna to support a rainforest or for it to be called a prairie.
There are actually two very different seasons in a savanna; a very dry reason (winter), and very wet season (summer). In the dry season only an average of about 10cm of rain falls. Between December and February no rain will fall at all. It is actually a little cooler during this dry season. But don't expect sweater weather: It is still around 21°C. In the summer there is lot of rain. In Africa the monsoon rains begin in May. An average of 38 to 64cm of rain falls during this time. It gets hot and very humid during the rainy season. Every day the hot, humid air above and turn into rain. In the afternoon on the summer savanna the rain pour down for hours.
Savannas have porous soil, with only a thin covering of nutrient. Savanna's soils contain usually low concentrations of nutrients. Still, Savanna's soil have nutrient equal to that of the rainforest's soils. During the dry season, surface water from the rain is quickly absorbed into the ground because the soil is extremely porous. Like a sandy sink a sluggish drain, the savanna hold rainwater. Rainwater slowly absorbs through a hard layer below the sand called hardpan. The marsh is sensitive to fluctuate in water level and as little as 15cm could mean the difference between wet prairie and pine flat woods. Some years, the floodwaters run freely through the pine forest on the western side.
Plants of savannas are special to grow in this environment of long periods of drought. They have long taproots that can reach the deep water table, thick bark to resist annual fires, trunks that can store water, and leaves that drop of during the winter to conserve water. The grasses are the most plant life in the savanna. Some grasses grow 180 to 270 cm tall. Some grasses are too sharp or bitter tasting for some animals. Many grasses grow from the bottom up, so that the growth tissue doesn't get damage by grazers. The grasses to live in the dry season and the fire, they have developed an adaptation that help them to grow quickly where there is enough water. Then when water becomes less, the grasses turn brown to limit water loss. They keep moisture and nutrients in their roots and have storage organs like bulb and corms while they wait for the rainy season coming. Trees usually grow alone in small dusters such as the acacia and baobab trees are common in African savannas.
Most of the animals on the savanna have long legs or wings to be able to go on long migrations., Many burrow underground to avoid the heat or raise their young. Animals like lions; zebras, elephants, and giraffe's and many types of ungulates (animals with hooves) graze and bunt. Many large grass-eating mammals (herbivores) can survive here because they can move around and eat the plentiful grass. There are a lot of carnivores (meat eaters) that eat them in turn. The savanna is a perfect place for birds of prey like hawks and buzzards. The wide, open plain provides them with a clear view of their prey, hot air updrafts keep them soaring, and there is the occasional tree to rest on or nest in. Animals don't sweat to lose body heat, so they lose it though panting or through large areas of exposed skin, or ears, like those of the elephants. During the rainy season, more birds, insects, both small and large mammals appears in savanna. During the dry season, most birds and large mammals move to search for water. When drought conditions exist for a long time, the animals may go to another biomes until the rainy season begins again.
Savannas have a hot and dry climate with the temperatures range from 17.9°C to 22.4°C. It has different kind of animals and plants. They all depend on each other to keep the environment in balance. It has two different seasons; a very dry season, and a very wet season. Burning the forest by the sacred fires creates it. Large animals also can turn the forest to savanna by knocking down the trees.

In the Savannah, a grassland which have a few trees, the temperate is about 17-22.4°C. This temperature is able for many animals such as lions, elephants, zebras, etc. In the quiet colors grassland, a lion want to hunt the zebra, although the zebra run faster and faster, the lion can catch it by their skill, then killed it by this sharp teeth and tear off the zebra's meat. The rainfall in Savannah are 100-400mm, so very birds like Lark Sparrow and Lark Bunting will be produce and feed their body in the Baobab tree. But in the winter, it will be cool to under 17°C to 14° C.

The name of the biome is arctic tundra and an easy location you can find an arctic tundra is Greenland located in the Northern hemisphere, encircling the North Pole and extending to the South Pole, arctic tundra cover about 1/5 of earth's surface. It has a frost molded boggy-like landscape. The biggest arctic tundra is the northern arctic coastal plain, which is 49,500 sq. km. It is level plain that is less than 300 meters in elevation. It is extremely cold in the arctic. In the winter, it averages around -34°C. The coldest occurs in North Eastern Siberia. In the summer it averages around 7°C. The warmest also occur in North Eastern Siberia. The annual precipitation is very low throughout the year. It is only 18cm in rain. The organisms. There are mostly dead and organic materials, which function as a nutrient pool. There are many organisms that have adapted to this tundra. An example is a polar bear; it has a layer of fat that keeps it warm.
The arctic tundra's environment is very unique. It has many plants and trees. Grows some vegetation by permafrost, which is a permanently subsoil limits the rooting depths of plant and forces the soil. Grows in sedges, dwarf shrubs, lichens, mosses, dwarf birch, Labrador tea and cinquefoil. It produces up to 227 to 454 kilograms per acre. It is grown is soil that are wet and can be well drained loamy with permafrost and ice. During the summer, where the daylight is very long, it has intense growing seasons. It grows mostly roots, berries, leaves, and seeds grow during that period. It has upland, which have poorly drained clayey soil. Shores and Lake Area provide many habitats for the organisms. The distribution of the permanently frozen subsoil may severely damage this fragile ecosystem. Most of the habitat survives from hibernation and migration. The precipitation is spread evenly during the year because of the 20-30 cm of rain that spreads on the flat grounds in areas of poor drainage, which becomes swampy during the summer months.
There are 2,500 kinds of lichens growing in the arctic which there are algae and fungus is presented. The number of plants is very few and the growth is low and most of the biomass concentrates on the roots. Its growing season is shorts and it's likely to grow very few. All of the plants have adapted to sweeping winds and disturbance of the soil. The plants are short and group together to resist the cold temperature and are protected by the snow during the winter season. They can carry photosynthesis to live at low temperature and at low light intensities. There are well known animals that are now living there because they have adapted in that area and they can provide for their needs there too. A few examples that have adapted to living here are the arctic fox and the polar bear. The arctic tundra is the coldest of all biomes with temperatures averaging below zero degrees. There are many habitats that have adapted to the area or have lived some place else because of its freezing temperature. Do to its cold temperature and very less rainfall, the plants do not grow very much. The environment is located at the top of the latitude. It has an unusual daylight during the seasons and part of the temperature is affected by the sunlight being away from the area during the winter with about only an hour of sunlight a day. During the summer where there is about 24 hours of sunlight, the heat melts the frozen particles that were left from the winter and causes it to make a lot of things look like slush especially the soil use to grow plants. The sun melts the permafrost away. That is one of the big factors why plants don't grow much here in the arctic. Different lifestyles have occurred here for the animals and the plants. The reason is to survive the cold temperature. Some animals migrate to other places and plants use the soil or bundle together. This is an extreme place. Covering 20% of the Earth's surface, it covers most of the northern part of the earth. A reason for that is because of the sun facing the different axis of the earth. The arctic is located in the northern axis. Its cold because the sun is facing the southern axis which causes the northern to be cold and the southern to be hot. When the sun faces the north axis, the sun will make the tundra warm but due to its cold temperature, the sun will not make it hot. Same goes to the southern axis.

Biomes is a place where animals and plants live. The Biome my group has is Grassland. Grasslands can be located all around the world. One specific place where you can find the Biome Grassland is the Great Plains of North America and also Grasslands are found in every continent except Antarctica. Grasslands are very open and empty with flat areas of grass. The grasses can be 25cm to 165cm tall, with the roots going down to 75 to 150cm deep in the ground. The grass length is depended on the rainfall it receives. The Grasslands receive 50 to 90cm of rain per year, unlike the Desert Biome which only receives 30cm and less per year. That can seem very small compared to the Tropical Forest Biome which has 200cm rainfall per year. Some of the organism that you can find in the Grasslands are the bird called buzzard and the brown longearad bat and a bug called common dor beetle. Those are just some of the many organism in Grasslands. Grasslands is one of the most peaceful Biomes in the world.
The Grasslands are very grassy and has a lot of dirt and soil and trees, it's very similar to the Desert Biome. It does not rain much in the Grassland so there is barely any water cycle happening during the year. Grassland have an average rainfall compared to other Biomes. Grasslands are between Tropical Rainforest and the Desert in rainfall averages in the year. The Grassland are often called the breadbaskets of the world because its soil and land are where the farms are at which grow the nutrient food everybody eats.
The plants in the Grassland Biome are very beautiful will bright colors with a lot of pollen. A lot of plants in the Grassland Biomes are in a lot of gardens in peoples backyards. Here are some plants from the Grassland Biomes milkweed flower, a blazingstar flower that can be has tall has up to up to 152cm. Another plant is a purple coneflower these plants can also be seen in peoples yards. An aster plant is also in the Grassland Biome that has a very bright color of purple. The stinging needle plant looks like a normal plant from for away but when you go up close and touch it with your bare hands you will get a stinging pain by the plant. This plant can grow up to 91.2cm.
Most animals in the Grassland Biomes are big and strong animals like the Elephant who eats up to 440 pounds of food a day. Its diet may include up to leaves, shoots, twigs, roots, and fruits. The other animal is another very big animal which is the bison which was very close to extinction by the European settlers in the early twentieth century. There are now over 20,000 bison in the Grasslands thanks to the American Bison Society. The male may be as much as 2.9m at the shoulders, which are humped and covered with the shaggy, brownish-black fur that also grows thickly on the head, neck and forelegs. The girls looks similar to the guys but is smaller; young are more reddish-brown. The giraffe is a the tallest animal in the Grasslands. The giraffe can be 14 feet tall. The giraffe goes with 6 to 12 other giraffes in herd maybe even more. The lion is a splendid, powerfully built cat, the lion has a broad head, thick, strong legs and a long tail tipped with a tuft of hair that conceals a claw-like spine. The color of the lion varies to tawny yellow to reddish brown. The lion spends 20 or more hours a resting. They live in groups, known as prides, consisting of up to 3 adult males and up to 15 females and their young in a territory that is defended against intruders, particularly other mature male lions.
So in conclusion the Grassland Biome is very open and empty with plants and tall grasses with tons of great animals. The Grassland does not have much of a water supply, but when it does rain that's when the animals are most active. The Grasslands plants are very colorful and bright. The plants you see in the Grassland you can also see in peoples yards. The animals in the Biome are very big like the lions, the bison, the giraffes, and the elephants. The Grasslands are probably the most peaceful Biome in the world.

Presenter's Outline
Good evening class I am Derell. my group Foshow Lil Daddy did our Biome on grassland. We choose grassland because we all felt we didn't no a lot about that Biome. Looking up grassland wasn't easy we had to search a lot of sites to get all the Information that we got.

Dry, sandy, and hot, those are few best words that best describe the desert biome. This biome is located in several areas throughout the world. This biome is located in several areas throughout the world. Some of the major deserts are located in different countries like North America, Saharan, Iranian, Turkestan, Takla Makan-Gobi, Thar, Atacams, Patagonian, Namib, Kalahari, and Austrialian. To just name a few mammals that lives in the desert are antelopes, armadillo, bilby, red fox, fennec fox, great jerboa, mouse tailed bat, and many more. The desert is not like any other biomes or places it is extremely hot and it only receive an average of less than 25cm of precipitation a year. As for temperatures though it may be exceed to 82°C on summer or higher in the afternoons but it can dip to 20-30 degrees or more at night.
Like I said before it does not rain very much compare to the other biomes. It only rains 25cm once a year. When it rains the plants absorbs all the water it can, like the cacti who store its water in their stems and use it very slowly, and the bushes who use the water from the plants that has absorb the water from the rain. Also unlike the other biomes, the deserts can have very mild winters while the other has freezing winters. The desert is also of course the driest of all and it only gets 10 percent of rainfall that the rainforest gets.
The plants in the desert is able to survive in the desert is because that they have adaptations. Adaptations are the certain type of behavior the plants has to keep them survives. Most plants have two abilities and they area to be able to collect water and store them. The other one is that it has features that reduce water loss. Like the barrel cactus, which has pleats that let it expand when it rains, and store the water in its spongy tissue.
It can also shrink in size during times that it is drying as it uses the water being stored. Another example is the ocotillo that has stomata, which is the little holes underneath the side of a leaf that is able to let air get into the plants. Other plants that are similar to the ocotillo plants has very small leaves and therefore it has very few stomata and that makes sure of it that the water inside the plants would not be evaporating so fast. Many plants have a waxy surface to soothe and pain of bums.
Life in the desert for the animal is obvious pretty complicate with the lack of water and the high temperatures. In order for them to stay alive they would have to avoid the heat. Some animals in the desert like the kangaroo rat, red fox, fennec fox, rattle snakes spends most of their time underground and some only come out to eat and hunt at night are called the nocturnal. As for smaller mammals and reptiles they are only active at dusk again at dawn, which is called crepuscular.
Overall the desert would not be a good place to live at since it is a pretty intense area to live, it is very hot and dry. Also in a way it is very interesting being able to understand more how the animals can live in the deserts surviving. It is one of the challenges that the animal has to face through in the desert. They are fighting to survive in the tough life in the desert. The desert is located in several areas and it is mostly located near the equator. In closure the desert has intense heat than the other biomes and I am sure that without much water out there I will not be able to stand the climate out there.

Our world has nine different interesting biomes, includes tundra, grassland, tropical rain forest, ocean, dessert, Savannah, temperate rain forest, deciduous forest and coniferous forest. My group mates and I are researching about tropical rain forests in the world. Tropical rain forests are found mostly near the equator because of its hot temperature and wet, rainy seasons. There are several main regions and countries that have the biome of tropical rain forest, that includes Brazil, Philippines, Central America, Indonesia, countries around Cuba, Gabon, Thailand, Cambodia, Burma, eastern India and Malaysia. Tropical rain forest is mostly covered up by tropical trees and a body of water surrounding the land. The environment there is really hot that the temperature is 20 to 35OC high. There are many animals living in this environment, some main ones includes tigers, jaguars, snakes, monkey, birds, etc. Some typical organisms includes humming birds, jaguars, and toucans. Tropical rain forests has a very high rate of rain fall each year, annually it has over 256 cm of rain fall.
The tropical rain forest, also known as selva, is the earth's most complex biome in terms of both structure and species diversity. It occurs under optimal growing conditions: abundant precipitation and year round warmth. There is no annual rhythm to the forest; rather each species has evolved its own flowering and fruiting seasons. Sunlight is a major limiting factor since all the trees needs it to grow and spread out the land. Tropical rain forest's monthly temperatures are above 25°C; precipitation is often over 256cm per year. There is usually a brief season of reduced precipitation. In some areas, there is a real dry season, but that is more than compensated for with abundant precipitation the rest of the year. Tropical Rain Forests have a layered structure with the middle layer forming a canopy of intertwined branches. Tall trees are above the canopy up to 45m. There is a lower layer of shade-tolerant trees, but the forest floor is open due the fact that little sunlight reaches the forest floor. Many trees have leaves with drip tips that channel the water off the leaves. The soils are not high in nutrients because the trees, plants and other organisms holds most of the nutrients. The forest's water cycle is basically the same as other areas, where the ocean water is being evaporated by sun light and becomes water vapor, then vapor rises and condenses and eventually forms a cloud that can't hold anymore vapor, and water drops begin to fall in different forms known as precipitation, that includes rain, drizzle, snow, hail, sleet, and fog. But this region's rain fall was higher because it's very hot there and the ocean eventually evaporates more than normal regions, that's why the rain fall in that area is much higher.
There are tons of typical plants and trees found in this biome. There are over 180 kinds of trees in tropical rain forest and all of them are extremely tall and receives much nutrients from the soil. Various growth forms represent strategies to reach sunlight, and some of the examples of these trees includes epiphytes, lianas, climbers, stranglers, and heterotrophs. There are common characteristics of tropical trees. Tropical species frequently possess one or more of the following attributes not seen in trees of higher latitudes. Some common ones are buttresses, large leaves, and drip tips. The tree branches are tangled up and the trees are surviving by receiving sun lights from sun, water source from ocean, and nutrients from soil.
