Have kids consider where a given kind of animal, e.g., tree squirrels, naturally live. The woodlands where tree squirrels live are its natural habitat. Similarly, grasslands with patches of scrub where rabbits may be found are the rabbit’s natural habitat. Generalizing, the adaptations of each species of animal make it particularly suited to live in a certain sort of habitat. An animal’s natural habitat provide it with necessary food (kinds of plants), water, places to hide from predators, raise its young, etc.
