What type of sunlight does the rainforest get?
Tropical Rainforest: Plants Although tropical rainforests receive 12 hours of sunlight daily, less than 2% of that sunlight ever reaches the ground. The tropical rainforest has dense vegetation, often forming three different layers–the canopy, the understory, and the ground layer.
How much sunlight does each layer of the rainforest get?
The canopy is home to 90% of the organisms found in the rain forest; many seeking the brighter light in the treetops. The forest floor receives less than 2% of the sunlight and consequently, little grows here except plants adapted to very low light….

Why can light not filtered through the canopy of trees?
Because of the very dense canopy, little sunlight reaches the ground. In a dense forest, the canopy trees can block out over 95% of the sunlight.
How much light reaches the canopy?
The canopy is an interlocking network of sun-hungry leaves. It is so efficient that only between three and 15 percent of sunlight penetrates. Not all of the light is caught by the topmost leaves.
How much sunlight reaches the understory?
The Understory Layer Unlike the emergent layer, there is hardly any air movement; this results in high humidity, but still provides constant shade. Receiving only 2-15% of the sunlight that falls on the canopy, the understory is a rather dark place and houses the jaguars, red-eyed tree frogs, and leopards.
How are short plants growing below thick canopies?
In tropical rainforests, the canopy is thick and shorter plants growing below it receive filtered light. They have evolved and can photosynthesize in low-light conditions. They have more photosynthetic units and they photosynthesize using filtered light.
How do the small plants in tropical forests carry out photosynthesis?
1 Answer. In tropical rain forests, the canopy is thick and shorter plants growing below it called sciophytes (shade loving plants). They can photosynthesise in very low light conditions. They have larger photosynthetic units and hence they are able to carry out photosynthesis in filtered light.
