Detailed explanation-1: -The term hibernation is also used to delineate the dormant state only during winter. In arid regions a reverse phenomenon is seen in which the animal becomes torpid during the hot, dry, barren summer; such hibernation is called estivation.

Detailed explanation-2: -Estivation is when animals slow their activity for the hot, dry summer months. During a period of estivation, many reptiles go underground where it’s cooler. Estivation is very similar to hibernation, when some mammals spend the winter moving very little and sleeping a lot, in order to save energy.

Detailed explanation-3: -Estivation is when animals are dormant because weather conditions are very hot and dry. Their breathing rate, heart rate and metabolic rate decrease to conserve energy under these harsh conditions.

Detailed explanation-4: -Hibernation or “winter sleep” is the state of inactivity or low metabolic process animals perform during winter. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summer.

Detailed explanation-5: -Ans: Hibernation is a period of dormancy during the winter months, also known as winter sleep. It is distinguished by a significantly reduced metabolic rate and the consumption of only reserve food. Diapause is a type of aestivation in which morphological growth and development are suspended during the summer months.
