The Tropical Rainforest Biome

By Gavin Vogt

Tropical Rainforest Facts• Tropical rainforests are located in warm regions.• 50-260 inches of rain falls every year.• 40% of Earth’s oxygen comes from tropical

rainforests.• Rainforests are now less that 6% of Earth’s

surface.• 70% of the plants in rainforests are trees.• Rosy periwinkle can heal a person of

lymphocytic leukemia.

Tropical Rainforest Facts• ¼ of today’s medicines come from the rainforest.• There are more than 2, 500 types of vines in the

tropical rainforest, some as thick as a human.• About half of all species of plants and animals

live in the rainforest.• Bird droppings in the tropical rainforest grow

into trees.• There have been tropical rainforests since

dinosaurs lived.

Layers of the Rainforest

• There are four main layers of the rainforest.• The emergent layer has the tallest trees and

animals such as monkeys and eagles live here.• The most animals live in the canopy layer

because it has fruit in abundance.• In the understory layer there are few plants and

animals such as frogs and jaguars.• The forest floor is very dark and almost no

plants grow.

Layers of the Rainforest• The trees in the emergent

layer are usually evergreens and can grow to 200 feet high.

• Trees with smooth, oval leaves live in the canopy layer.

• Trees in the understory layer have large leaves to reach sunlight but rarely grow to 12 feet.

• Herbs grow on the forest floor.

Animal Life

• A new species of elephant, a forest elephant, was discovered in the rainforest.

• Orangutans are the largest tree dwelling apes in the tropical rainforests of Southeast Asia.

• Chimpanzee communities have 15-100 chimps.• The Bengal tiger prefers to kill young or old

animals because they are not as fast.• When a King Cobra is born, its venom is as strong

as an adult’s venom.
