What happens to an animal when it hibernates?

Answer 1

Hibernation is an inactive, sleep-like state for extended periods that some animals enter during extreme winters to remain alive without food for long periods. The body temperature of a hibernating animal is lower than normal. Also its heartbeat and breathing slows down considerably.

In winters when the environment is very cold and food is scarce, hibernation enables these animals to remain alive without food in three ways. First the body temperature of the animals is reduced below the normal temperature, reducing the expenditure in energy in keeping the body warm. Second, lack of physical activity also cuts down on energy requirements. Finally these animals have a large reservoir of fat stored in the body which is used up during the period of hibernation.

Hibernation for some animals can last for several weeks stretching across the worst period of winter. For others the hibernation may consist of several stretches of a few days interrupted by in between periods of arousal when the body temperature is restored to normal.

Answer 2

During hibernation, an animal's metabolic rate and body temperature decrease significantly to help conserve energy. They enter a state of dormancy where they are able to survive for extended periods without eating or moving much. Their heart rate and breathing slow down, allowing them to conserve energy until winter ends.

Answer 3

One thing that happens it that its breathing reduces.

Answer 4

when Animals go into Hibernation it means that they sleep from the start of winter to the end.
