Q 7.The tropicals rainforests has a large population of animals.Explain why it is so?

Answer:The atmosphere of tropical rainforest is generally hot and humid with hot showers. These hospitable climatic conditions support the vast population of plants and animals.

Q 8.Explain with example, why we find animal of certain kind living in particular climatic condition.

Answer:Some types of animals can be found in special climatic conditions because they can adapt well to those conditions. For example, a polar bear is optimized for polar areas. To keep it warm in cold conditions, it has a thick skin and a layer of fat. However, with these adaptations, it will not be possible to survive in the tropical zone where it is hot. Similarly, a monkey is adapted to live in the forest, which has facilities like long and strong tail, loud sound, etc. These facilities have no significance in polar regions where there is very little vegetation. Therefore, some types of animals live only in some climate conditions.
