Migration, Hibernation, Dormancy, Camaflage, Estivation
Migration is the movement of species to new climates. Hibernation is the change of animals to inactivity to adapt to the cold weather. Dormancy is a period of inactivity that stops physical growth. Camouflage is used to conceal an organism within its surroundings. Estivation is similar to hibernation, but occurs during the summer.
