The trees get lots of sunlight.  The tallest trees of the rainforest are in the emergent layer.  Some trees grow 200 feet tall.

The trees get sunlight and are also tall here.  Lots of fruits and flowers grow here.  This is the main layer of the rainforest.

This layer of the rainforest does not get much light.  The canopy layer blocks the sunlight.  Plants grow up to 12 feet high.

Almost no sun reaches this layer.  It is very wet and warm in this layer.  Things rot quickly here.
