EVERYDAY SCIENCE

Detailed explanation-1: -Hibernation: a dormant, inactive state in which normal body activities slow. Migration: the movement of animals from one region to another and back.

Detailed explanation-2: -Hibernation or “winter sleep” is the state of inactivity or low metabolic process animals perform during winter. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summer.

Detailed explanation-3: -For example, salmon start life in rivers and migrate to the sea to feed and grow. After spending up to seven years in the ocean, they migrate back to the rivers they were born in so that they can spawn. Christmas Island red crabs (Gecarcoidea natalis) migrate for similar reasons.

Detailed explanation-4: -Animal migration is the large-scale movement of a species from one place to another. Most species migrate during specific seasons, in search of food or water, or for mating reasons.
