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.

1.vines, small trees, massive trees
2. 75,10,25

1. massive trees 2. 75

Explanation:

A canopy is over 100 meters hence the top layer of the dense rainforest will be the of the massive trees, and the top layers are more warm and dry as compared to the bottom and ground layer that are not as exposed as the top layers are as the evergreen are broad leafy trees and have many species that depend on this for there survival. Thus the canopy is the thickest layer and is dense and has tall and giant trees that make up this layer. Many emergent trees that tower above them have a height that exceeds more than 210 meters and thus stretches to longer distances.
