Animals are born, grow up, and have young of their own, and so the life cycle continues.
A butterfly changes from egg to caterpillar to chrysalis to adult, while a frog and a chicken grow through their own stages.
A pupa stage, like the butterfly's, means complete metamorphosis; growing with no pupa, like a grasshopper, is incomplete.
Here you can choose an animal to follow its life cycle around the circle and compare the two kinds of metamorphosis.
