*     Adaptation in Animals


Animals have unique capacity to adapt themselves to survive in their surroundings.


Animals adapt themselves for the following:

(A) To live in a particular area

(B) To protect themselves from enemies

(C) To protect themselves from the extreme conditions or weather

(D) To overcome food scarcity

Animals living in cold places have thick layer of fat inside their skin to provide warmth to the body. For example: Polar bear that lives in extreme cold conditions of poles. Animals of hot areas like deserts, have thick skin with less hair to protect themselves from hot conditions. For example: Camels. Animal like zebra has stripes on their body to protect themselves from enemies. Similarly chameleon changes its colour according to the surrounding. Few animals undergo hibernation and few animals undergo aestivation process to hide themselves from the extreme hot and cold conditions. In hibernation frogs, snakes, snails, polar bear etc. go underground to sleep for a long period in winter. Whereas animals like crocodiles salamanders become inactive in summer called as aestivation. Snakes and lizards have scaly skin to protect themselves from drying





     Aestivation and hibernation are adaptation against

(a) Protection from enemies

(b) Extreme hot and cold condition

(c) Living in a particular area

(d) Both (a) and (b)

(e) None of these                                         


Answer: (b)


When the weather is too cold, animals go into burrows for long sleep called hibernation. Similarly when weather is too hot they go for aestivation. Therefore, option (b) is correct and rest of the options is incorrect.



       The animal in the given figure has:

(a) Thick skin with less hair

(b) Thin skin with more hair

(c) Thick layer of fat under skin

(d) Thick layer of fur on their body

(e) Both (c) and (d)


Answer: (e)


Polar bear lives in extreme cold condition. They have thick fur on their body and is also a thick layer of fat under skin to protect themselves from cold. Therefore, option (e) is correct and rest of the options is incorrect.
