Why do Tropical Rainforests have large populations of animals?

Hint: Tropical rainforests are a type of rainforest, which occur in tropical rainforest climates. Tropical rainforest is also called lowland equatorial evergreen rainforest. They are called rainforests because of the higher amount of rainfall, which is present in tropical regions. Fiji, Burma, Malaysia, Philippines, Thailand and Indonesia are the countries, whole areas cover mainly tropical rainforests.

Complete answer:
Tropical rainforests exhibit a very favorable climate and provide different kinds of foods easily. They are humid and hot with the presence of ample rainfall, which play a main role in the growth of plants and animals.
Any population needs enough availability of resources for its growth and survival. These forests are enriched with necessary resources because of the higher amount of rainfall, which is a requisite for creation of the resources. They have continuous warmth and rainfall in their regions, supporting a broad range of plant and animal varieties.
Normally the climate is hot, but minimum temperature attains \[15^\circ \]C. The maximum temperature crosses \[40^\circ \]C in hot summers. Throughout the year, nights and days are equal in length. Due to this continuous warmth, insects, birds, lizards, leopards, elephants, tigers, apes, gorillas and monkeys dwell there.

Note:
Tropical rainforests are present in south and central America, central and western Africa, New Guinea, western India, southeast Asia and Australia. They cover less than three percent of the earth’s area. They constitute one of the largest biomes in the world. They are distributed across \[4.9\] billion across the world. Indeed, over \[50\% \] of plants and animals of the world reside here.
