What type of sunlight does the rainforest have?
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.
What lives on the forest floor?
Decomposers, such as termites, slugs, scorpions, worms, and fungi, thrive on the forest floor. Organic matter falls from trees and plants, and these organisms break down the decaying material into nutrients. The shallow roots of rainforest trees absorb these nutrients, and dozens of predators consume the decomposers!
What fruit grows in the rainforest?
Fruits like avocado, coconuts, oranges, lemons, grapefruits, bananas, pineapples, mangoes and tomatoes can all be found in the world’s rainforests, along with vegetables such as: maize or sweetcorn, potatoes, and winter squash.

EMERGENT LAYER The tallest trees are the emergents, towering as much as 200 feet above the forest floor with trunks that measure up to 16 feet around. Most of these trees are broad-leaved, hardwood evergreens. Sunlight is plentiful up here.

Threats
- Logging interests cut down rain forest trees for timber used in flooring, furniture, and other items.
- Power plants and other industries cut and burn trees to generate electricity.
- The paper industry turns huge tracts of rain forest trees into pulp.
- The cattle industry uses slash-and-burn techniques to clear ranch land.
