What can you find in the top layer of dense canopies in rainforests? The top layer has that grow to heights of meter(s) or more, which does not allow much sunlight to enter the canopy.

Answers

The canopy of a rainforest is defined as the top layer present 30 meters above the ground, which is made up of the overlapping leaves and branches of the trees.

The top layer of the canopies is known as the emergent layer that consists of a large number of trees and extends in height to all the plants.

What is the canopy of the rainforest?

The long and enormous trees of the rainforest are extended to reach the direct sunlight. The canopy formed due to the overlapping of trees blocks out the sunlight available to the plants present beneath the canopy.

60-90% of the life forms are found in the canopy of the rainforests. It is one of the richest habitats and has biodiversity.

The root system of the rainforests is shallow, and the bark is thin and smooth as the rainforests do not deal with cold weather.

Thus, the canopy reaches a height of more than 30 meters to achieve direct sunlight.
