Answer 2

There are several animals that hibernate during the Winter to await the coming of Spring and warmer temperatures. Hibernation is often used during a time when food is scarce. Animals put on body fat during the Autumn, which they live on when hibernating. Hibernation is when an animal goes into a deep sleep, the heart and breathing rate is slowed, and provided there is enough stored body fat for the animal to live on, the animal should survive until the return of their food source in Spring.
