Forest floor
Explanation:
Tropical rainforest is characterized by high rainfall that allows a diverse growth of plant species. The different species of plants and animals species that make up a rainforest are found in different layers. There are four layers or sections in the rainforest from top to bottom viz: emergent layer, canopy, understory and forest floor.
Since the layers are classified from top to bottom, each layer receives different amount of rainfall and sunlight.
