Question 8:

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


Animals are adapted to the conditions in which they live. These adaptations are the just because of long process of evolution. It would be difficult for them to survive if they are moved to region having different climate conditions than from their habitat. Consider the following examples:

  • A polar bear has thick layer of fat under their skin which acts heat insulator. It protects the bear from extreme cold climate of polar region. The polar bear cannot survive if it is moved to hot and dry desert region.
  • Monkeys have long tails for grasping branches adapted to live in tropical rain forests. It cannot survive in Polar Regions.

Question 9:

How do elephant living in the tropical rainforest adapt itself?


It has adapted to the conditions of rainforests in many remarkable ways. It uses its trunk 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 is able to 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 rainforest.
