Types of rainforests

There are two types of rainforests, temperate and tropical.


The Temperate Rainforest are found around the coastal and temperate regions of the world including North America, Chile, The UK and other places. Tropical rainforests are located in Central and South America, Africa, Australia, and Southeast Asia. It is mostly found in the areas by the equator. One welly none rainforest area is the Tropical Rainforest of the Amazon in South America.

How have organisms adapted/varied due to it's eviroment

Almost all the animals/ organisms that live in the tropical rainforest have adaptations that allow them to live in the trees. For example monkeys have prehensile tails that can wrap around branches allowing monkeys to hold on to the trees with there tails. Some organisms have genetically varied to survive in there enviroments. For example, many insects are camoflauged to blend in with the rainforest floors and trees to protect them from predators.


Rainforest weather is very important because it helps maintain global weather patterns and rain. When water evaporates from trees , it falls in other areas as rain. In tropical rainforests , it is lush and warm all year long. Temperatures do not change much. The average temperature is 70 to 85°F. It is wet in tropical rainforests with a high humidity of 77% to 88% yearly.The year round rainfall is 80 to 400 inches. It can rain very hard! It can downpour up to 2 inches in a hour. Temperate rainforests are not as rainy as tropical rainforests. It rains around 60-200 inches each year. The moisture comes from coastal fog spend a long time on the trees. The fog gives 7-12 inches of rain yearly. In temperate rainforests it is cooler but still mild. They often have a wet winter and short dry summer.

Description of interdependency between organisms

Animals reply on plants and vice versa. For example, Birds drop seeds and they grow into new plants. This helps the rainforest survive! In return, tropical rainforests have migration destination in the winter. Another example is trees protects many animals that live on the forest floor from wind and rain. These animals rely on the trees


An example of variations is the different colors of birds for where they live. A bird that lives in the rainforest is brightly colored while a bird that lives in the desert is brown. Another example of variations in the rainforest are snakes. Many snakes that live in the trees of the rainforest are green because it helps camouflage them while many snakes that live in the desert are sandy brown so they can blend into their environment.


Many types of animals have to adapted to be able to live in certain environment. One example is the hummingbirds in the rainforest. These birds have adapted their diet and are the only birds in the rainforest that can survive on mostly just flower nectar. Another example is the Toucan bird. Its bill is adapted to be able to crush and saw food such as fruits and nuts.

Food web with the addition of the wild cat

Affect the Ecosystem

We added in a cat to the rainforest ecosystem that eats the crickets and is eaten by a large snake. We think that adding cats to the ecosystem would either result in an over population of animals that are mainly eaten by snakes, or it would force another tertiary consumer to eat the cat. Either way it would disrupt the food web and ecosystem.

Food Web with removal of Snake

We decided to remove the snake from the tropical rainforest biome. If the snake was removed from the ecosystem there were be to many shrews and frogs and they would soon over populate and kill off too many of the primary consumers and the ecosystem would be all out of whack.
