Detailed explanation-1: -An estimated 50-90 percent of life in the rainforest exists in the trees, above the shaded forest floor. Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor.

Detailed explanation-2: -Structure-The tropical rainforest is composed of three layers: the canopy, the understory, and the forest floor. The canopy is formed from the large trees whose crowns form a tight, continuous layer above the ground. The canopy is home to 90% of organisms found in the rainforest!

Detailed explanation-3: -The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers. The top layer or canopy contains giant trees that grow to heights of 75 m (about 250 ft) or more.

Detailed explanation-4: -The canopy: A tree top power station An estimated 50-90% of life in the rainforest lives up in the trees-swinging, squawking and slithering through the branches. The canopy is the main site of interchange for energy, water vapor and atmospheric gasses like oxygen and carbon dioxide.

Detailed explanation-5: -Many well-known animals including monkeys, frogs, lizards, birds, snakes, sloths, and small cats are found in the canopy. The conditions of the canopy are very different from the conditions of the forest floor.
