4. The tropical rain forest has a large population of animals. Explain why it is so.

Ans: The tropical rain forest has a large population of animals because they experience continuous warmth and rain throughout the year. Such climatic conditions in rain forests are highly suitable for supporting an enormous number and variety of plants and animals.

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

Ans: We find animals of certain kind living in particular climatic conditions because animals are adapted to survive in the conditions in which they live. Animals living in very cold and hot climate must possess special features to protect themselves against the extreme cold or heat.

For Example, animals in the polar region like polar bears are adapted to the extremely cold climate by having some special characteristics such as white fur, strong sense of smell, a layer of fat under the skin, wide and large paws for swimming and walking, etc.

Polar bears have white fur so that they are not easily visible in the snowy white background. It protects them from their predators. It also helps them in catching their prey. To protect them from extreme cold, they have two thick layers of fur. They also have a layer of fat under their skin. Its paws are wide and large, which help it not only to swim well but also walk with ease in the snow. While swimming underwater, it can close its nostrils and can remain underwater for long durations. It has a strong sense of smell so that it can catch its prey for food.

6. How do elephant living in the tropical rain forest adapt itself?

Ans: An elephant living in the tropical rain forest, has adapted to the conditions of rain forests in many remarkable ways.

• Look at its trunk. It uses it as a nose because of which it has a strong sense of smell. The trunk is also used by it for picking up food.

• Moreover, its tusks are modified teeth. These can tear the bark of trees that elephant loves to eat. So, the elephant can handle the competition for food rather well.

• Large ears of the elephant help it to hear even very soft sounds. They also help the elephant to keep cool in the hot and humid climate of the rain forests
