Answer 2

Answer:

Hibernation

Explanation:

    Hibernation is a survival mechanism used by many animals in periods when environmental conditions are very adverse or when the amount of food available is less than necessary to maintain the animal's body temperature.

    Small animals are more likely to hibernate because their metabolism is usually very fast depending on a large amount of energy to keep warm.
