Detailed explanation-1: -Hibernation is a hypothermic condition when animals save energy during cold seasons by lowering body temperature, metabolism, breathing, and heart rate. This makes it possible for an animal to survive the winter on a fat deposit that would otherwise not last the winter.

Detailed explanation-2: -This can be a challenge when freezing weather comes along or when food is scarce. 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. The body temperature is set at a new, lower point.

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: -Hibernation is a deep sleep that helps them to save energy and survive the winter without eating much. During hibernation the animal’s body temperature drops, and its heartbeat and its breathing slow down so that it does not use much energy.

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.
