Q
Weather, Climate and Adaptations of Animals to Climate

Question:

Which features adapt polar bears to live in extremely cold climate?

(i) A white fur, fat below skin, keen sense of smell.

(ii) Thin skin, large eyes, a white fur.

(iii) A long tail, strong claws, white large paws.

(iv) White body, paws for swimming, gills for respiration.

Answer:

Polar bears have white fur so that they are not easily visible in the snowy white background. It protects them from their predators and helps them to catch their prey. They have a thick layer of fur which keeps them warm in cold weather. They have layers of fat under their skin which insulates their body and keeps it warm. That is why they move slowly and rest often to avoid getting overheated. They have long curved and sharp claws which help them to walk. They have wide and big paws which help in swimming. They can close their nostrils during swimming and can stay in water for a long time. They have a strong sense of smell which helps them in locating and catching their prey for food.

Hence, the correct answer is (i) A white fur, fat below skin, keen sense of smell.
