Science Quiz - Life Cycles - Animals (Questions)

Embark on an exciting journey of discovery with this KS2 Science quiz about life cycles! Learn about the stages of animals' lives, from birth to death.

Life cycles are the amazing stages from birth to death that all living things, including you, go through. Insects start as eggs, become larvae, then pupae, and finally adults. Humans begin as babies, grow into children and adolescents, and eventually become adults.
