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 temperature of the environment.
$1$. $Hibernation$ (winter sleep): During extreme cold,the metabolic rate of the frog decreases significantly to conserve energy and survive the harsh conditions where food is scarce.
$2$. $Aestivation$ (summer sleep): During extreme heat and dry conditions,frogs undergo aestivation to prevent excessive water loss through their skin and to protect themselves from dehydration.
These physiological adaptations allow frogs to survive in environments where temperature and moisture levels are not optimal for their active life.
