There are four layers of Tropical Rainforest:
-;Emergent layer
-;Canopy layer
-;Understory layer
-;Forest floor layer

Emergent layer---The tallest trees are emergent towering as much as 200 feet above the forest floor with trunks that measure upto 16 feet around.Most of these trees are broad leaved and hardwood evergreen.
Canopy layer----This is the primary layer of forest and forms a roof over the two remaining layers of forest.
Understory layer---It is the dark place as compared to canopy.It is relatively open and contains young trees.
Forest floor---It receives about 2%of the sunlight and the plants which are grown in this region are less in quantity because this region receives less sunlight.
