Answer:
It allows them to save energy
Explanation:
Hibernation is a behavioral adaptation that involves physiological changes to survive during wither months. These physiological changes can include a decrease in body temperature, respiratory/heart rate and metabolism. The main purpose for which animals enter hibernation is to conserve energy, thereby surviving adverse climatic conditions and/or periods when food is scarce. Some examples of true hibernators (i.e., animals that enter into a state of minimal activity) include bats, hedgehogs, allies, squirrels, marmots, etc.
