8. Explain, with examples, why we find animals of certain kind living in particular climatic conditions.

Answer:

Animals need a particular environment to survive. All the animals have a different and certain environment which suits them to survive.

Example: A polar bear leaves in cold and snowy regions because they have a thick and fat layer of skin which protects them from cold. They cannot survive in the desert area. Similarly, camel leaves in the desert region, they cannot survive in cold regions.

Thus, animals of a certain kind live in particular climatic conditions.
