Detailed explanation-1: -Hibernation is a physiological and behavioural adaptation whose function is to maximize energy efficiency in animals remaining in the same area the whole year round. It is an alternative to the provision of sufficient insulation to remain warm, forage continuously and sustain a constant high metabolic rate.

Detailed explanation-2: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-3: -Hibernation is a way for many creatures – from butterflies to bats – to survive cold, dark winters without having to forage for food or migrate to somewhere warmer. Instead, they turn down their metabolisms to save energy. Animals in hot climates also undergo a form of hibernation called aestivation.

Detailed explanation-4: -Behavioral adaptation: something an animal does usually in response to some type of external stimulus in order to survive. Hibernating during winter is an example of a behavioral adaptation.
