Hibernation and aestivation are both forms of dormancy shown by animals. Hibernation is a state of inactivity in which an animal reduces its metabolic rate and body temperature in order to survive during periods of low food availability, such as winter. Aestivation is a similar state of inactivity that occurs during periods of high heat and humidity, such as summer.
In both hibernation and aestivation, animals reduce their metabolic rate in order to conserve energy. This is done by slowing down the heart rate, breathing rate, and body temperature. Animals also reduce their activity level during hibernation and aestivation.
Hibernation and aestivation are both adaptations that allow animals to survive in extreme environments. Hibernation allows animals to survive the winter, when food is scarce. Aestivation allows animals to survive the summer, when the heat and humidity can be deadly.
Thermal adaptation is an adaptation that allows an animal to regulate its body temperature. Wind adaptation is an adaptation that allows an animal to cope with the effects of wind. Adaptation to escape from predators is an adaptation that allows an animal to avoid being eaten by predators.
Hibernation and aestivation are not adaptations to escape from predators. They are adaptations to survive in extreme environments.
