The tropical rainforest has a large population of animals. Explain why it is so.

Tropical rainforests contain the largest population of animals because they have favorable climatic conditions for animals' growth, survival, and reproduction.

The tropical region witnesses a hot climate due to its location near the equator. The temperature ranges from 15 degrees celsius to 40 degrees celsius. Length of day and night are equal throughout the year. It also gets ample rainfall due to its hot and humid climate which supports the growth of animals and plants.

Tropical rainforests avail a huge variety of foods for the animals.


Usually, the tropical rainforest is a darker, stiller, and more humid area that is a few meters below the canopy. Plants like palms and philodendrons are much shorter and have bigger leaves than the plants that make up most of the canopy. Large leaves on plants in the understory catch the little light that gets through the dense canopy.

The plants, like the Heliconia, native to the Americas and the South Pacific, often have big, easy-to-see flowers. Some of them, like orchids, have a strong smell. Even when there isn't much light in the understory, pollinators are drawn to these things.

In temperate rainforests, the fruit and seeds of a lot of the shrubs are available. Berries grow in temperate rainforests like the ones in North America.

There are many reasons for the animals to choose the rainforest to live as many animals use the dim lighting to hide. People might mistake the spots on a jaguar, which lives in the rainforests of Central and South America, for leaves or bits of light. In the Congo rainforest, the green mamba, one of the most dangerous snakes in the world, blends in with the plants as it climbs up branches. Many bats, birds, and bugs like the open space that the understory gives them. Amphibians, like brightly colored tree frogs, do well in humid places because their skin stays moist.

Some of the most endangered and well-known rainforest animals, like forest elephants, pythons, antelopes, and gorillas, live in the canopies and understories of the tropical rainforests in Central Africa.

Gorillas are herbivores that live in the dark, dense rainforest as well as swamps and jungles where there is more light. Their droppings spread seeds in these sunny places where new trees and bushes can grow.

The darkest part of a rainforest is the forest floor, that makes it very hard for plants to grow. When leaves land on the forest floor, they break down quickly. On the forest floor, things like termites, slugs, scorpions, worms, and fungi do well. The organic matter that falls from trees and plants is broken down by these organisms into food. These nutrients are taken up by the shallow roots of rainforest trees, and dozens of predators eat the decomposers.

Some tropical rainforests have rivers that run through them. These rivers create strange freshwater habitats on the forest floor. The boto, also called the pink river dolphin, lives in the Amazon River. It is one of the few dolphin species that live in freshwater. Black caimans, which are big reptiles related to alligators, live in the Amazon. The Nile crocodile, which is related to caimans and lives in the Congo River, lives in the Amazon.
