Give scientific reasons: Frogs undergo summer sleep and winter sleep (aestivation and hibernation).

(N/A) Frogs are poikilothermic (cold-blooded) animals,meaning their body temperature fluctuates with the ambient environmental temperature.
To protect themselves from extreme environmental conditions,such as the intense heat of summer and the freezing cold of winter,they seek shelter in deep burrows.
This state of inactivity during summer to avoid heat is known as aestivation,while the state of inactivity during winter to avoid cold is known as hibernation.
