Life Cycles & Reproduction

Every living thing follows a life cycle. A life cycle is the series of stages an organism passes through from the moment it begins to exist until it reproduces and the cycle starts again. Each stage has a job: some stages are for growing, others are for transforming, and the adult stage is for reproducing.
