Question 7:

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

Answer:

In tropical rainforest days and nights are almost equal in length throughout the year. The temperature of these region varies from 15°C to 40°C during the year. These regions get plenty of rainfall. Because of continuous warmth and rain, this region supports wide variety of plants and animals. The climatic conditions in rainforests are highly suitable for supporting an enormous number and a variety of animals. That is why the tropical rainforest has a large population of animals.
