Detailed explanation-1: -Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.

Detailed explanation-2: -In mountains where the temperature is low, animals undergo hibernation-like bears, wood frogs, etc. To avoid the external unfavorable environment, some animals hide in deep burrows. Winter sleep is also known as hibernation. Animals hibernate to escape harsh cold conditions.

Detailed explanation-3: -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-4: -Hibernation is when an animal slows its heart rate to save energy and survive the winter without eating much. Some animals just slow down and move less frequently during hibernation, but others go into a deep sleep and don’t wake up till spring.
