Explanation:
Tropical Rainforest Canopy Layers
The top layer of dense canopies in rainforests consists of trees that grow to heights of 30 to 55 meters, obstructing much sunlight from reaching the forest floor.
This dense canopy creates a shaded environment below, where only a sparse layer of plants and decaying matter exists, followed by an understory of short foliage.
The closed upper canopy, the highest layer, supports a diverse habitat for various organisms, forming a complex ecosystem within the tropical rainforest.
