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: -Hibernation is considered a seasonal adaptation to prolonged periods of food shortage and cold.

Detailed explanation-3: -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.

Detailed explanation-4: -Examples of behavioral adaptation include migration, hibernation, learned behavior, alteration in the mode of reproduction, altered feeding habits, and distinct modes of communication.

Detailed explanation-5: -Hibernating is a behavioral adaptation that allows the bear to snooze through the harshest part of the year when the temperatures are low and food is hard to find. Hibernating lowers the grizzly bear’s body temperature, heart rate, and need for energy.
