The life cycles of animals are the stages from birth to death. All living things grow and change, including you! The journey from birth, through growth and change, to death, is called the life cycle. For insects, it starts with an egg. Then a larva emerges. This becomes a pupa and finally an adult. Humans are born as babies. We then grow into children and adolescents before we become adults.
