Arrangement of vegetation
The arrangement of vegetation for a tropical rainforest is mainly forested. The exception being the rivers that flow through the forests. The vegetation is split into 4 layers: Emergent layer, Canopy layer, Understory layer, and Forest floor. The majority of light is blocked by the Canopy layer. This makes it harder for vegetation beneath this layer to survive. On the forest floor there is very little vegetation because it is difficult for photosynthesis to occur with limited sunlight.
