Emergent layer, canopy, understorey and forest floor are the four distinct layers of ___________.
Tropical rainforests or Natural forest have four layers:
Emergent Layer: These giant trees thrust above the dense canopy layer and have huge mushroom-shaped crowns.
Canopy Layer: The broad, irregular crowns of these trees form a tight, continuous canopy 60 to 90 feet above the ground.
Understory: Receiving only 2-15% of the sunlight that falls on the canopy, the understory is a dark place. It is relatively open and contains young trees and leafy herbaceous plants that tolerate low light. Many popular house plants come from this layer.
Forest Floor: The forest floor receives less than 2% of the sunlight and consequently, little grows here except plants adapted to very low light.
