Answer For,

Why does the organism engage in dormancy, hibernation, or migration?

Explanation:

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy.

Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time. Typically, animals hibernate in order to survive long periods when food is scarce.

Some animals travel relatively short distances to find food or more favorable living or breeding conditions. Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.
