Question

Aestivation of Frog occurs during
(A) Winter
(B) Summer
(C) Rainy Season
(D) Autumn

Answer 1

Hint: Aestivation is defined as the dormancy stage which occurs in response to summer. The dormancy stage is found in response to the water and food shortage condition. Dormancy is defined as the inactive stage in which the organism will not perform the activities but the organism is found in the inactive stage.

Complete answer:
Some organisms have dormant stages in which the individuals are found in inactive stages or they are found in resting conditions during its life cycle. The dormant stage is found in response to food shortage conditions. The food shortage means organisms don’t have enough food for their survival. That’s why there are found resting stages in such a period.
There are two types of adaptations are found on the basis of dormancy stages in the life cycle of an organisms:
Aestivation: Aestivation is also known as summer sleep. It is defined as the inactivity of organism during the summer season. There are found lower metabolic rates in the organisms during summer. Organisms are found in this state to avoid high temperature. It helps to prevent desiccation from the effect of summer. Examples of organisms which undergo aestivation: Crocodiles, salamanders, greater siren, frog etc.
Hibernation: Hibernation is also known as summer sleep. It is defined as the inactivity of an organism in response to winter. Because such organisms cannot survive in low temperatures. That’s why the organism undergoes a resting state in which metabolic activities of the organism decrease so that they can survive under shortage of food. Examples of organisms undergoing hibernation are: Woodchucks, Beer, snakes etc.
That’s why frogs undergo dormancy stages in summer. This summer sleep is known as aestivation.

Hence, the answer is “Summer”.

Note: Don’t confuse between aestivation and hibernation. Aestivation refers to summer sleep. Whereas Hibernation refers to the winter sleep. The dormant stage is found in aestivation and hibernation. This stage is found in response to food shortage conditions.
