life cycle
Definition
A life cycle is the different stages that a living thing goes through from birth to death. All living things have a life cycle, including plants, animals, and humans. The stages of a life cycle can vary depending on the organism, but some common stages include birth, growth, reproduction, and death.
For example, the life cycle of a butterfly starts with an egg. The egg hatches into a caterpillar, which eats and grows. The caterpillar then turns into a chrysalis, where it undergoes a major transformation. The chrysalis eventually opens, and a butterfly emerges. The butterfly flies around, mates, and lays eggs. The eggs hatch into caterpillars, and the cycle begins again.
