There are four layers to a rainforest. The bottom layer is the forest floor. Hardly any plants grow here because its very dark as the sun cannot get through the thick canopy of leaves. The forest floor is made of up quickly decomposing leaves. Many insects live in this layer, including ants that are preyed on by anteaters. 

The next layer is the understory. It is only a little lighter here so plants need to grow big leaves to catch the sun. 

A large amount of insects live here as well as tree frogs, leopards and jaguars. 

Above the understory is the canopy layer, the main part  or roof of a rainforest. Plants found in the canopy layer are epiphtyes, e.g orchids, lichens, mosses and ferns. and grow on the trunks, branches and leaves. 

Bromeliads are special epiphytes because they are mini ecosystems in themselves. They can collect water and are inhabited by frogs, salamanders, mosquito larvae and beetles.  

There is a lot of food for animals, such as snakes and toucans, to eat. The top is the emergent layer with the tallest trees, mostly evergreen. Monkeys, eagles, bats and butterflies can be found here. 

Rainforests provide us with medicines and food, e.g chocolate, sugar, pineapples and cinnamon, as well as other products like rubber.
