Here's why:
* Canopy: The dense canopy of leaves at the top of the rainforest blocks out most of the sunlight.
* Understory: The layer below the canopy, known as the understory, receives very little direct sunlight. This is where smaller trees, shrubs, and vines grow.
* Forest Floor: The forest floor is the darkest and receives the least amount of sunlight. Only about 2% of sunlight reaches the forest floor.
This is why the forest floor is often characterized by:
* Low light levels
* High humidity
* Decomposition of organic matter
* Specialized plants and animals adapted to low light conditions
