Detailed explanation-1: -Hibernation-is a cyclic response to cold temperatures and limited food supplies.

Detailed explanation-2: -Another example of a behavior with a ye arly cycle is hibernation. Hibernation is a state in which an animal’s body processes are slower than usual, and its body temperature falls. An animal uses less energy than usual during hibernation. This helps the animal survive during a time of year when food is scarce.

Detailed explanation-3: -Winter dormancy is a seasonal survival strategy common among temperate ectotherms, characterized by inactivity, fasting and low metabolic rates.

Detailed explanation-4: -Hibernation is a hypothermic condition when animals save energy during cold seasons by lowering body temperature, metabolism, breathing, and heart rate. This makes it possible for an animal to survive the winter on a fat deposit that would otherwise not last the winter.
