Detailed explanation-1: -So, in order to survive, many endothermic animals go into what’s known as a state of ‘torpor’. During torpor, physiological processes, like breathing and heart rate, slow down.

Detailed explanation-2: -When the animal’s body systems slow down it goes into a sleep-like state called torpor. Torpor in the summer is called estivation. Torpor in the winter is called hibernation.

Detailed explanation-3: -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-4: -Diapause is a dormant stage in the development of an organism. Hibernation is the reduction of metabolic activities in an organism. Diapause occurs during any time of the year. Hibernation usually occurs during the winter months.

Detailed explanation-5: -Torpor involves physiological changes related especially to body temperature, metabolism, and water balance. Hibernation is when an organism spends the winter in a state of dormancy; it is long-term multiday torpor for survival of cold conditions. Estivation is summer dormancy, for survival of hot and dry periods.
