Animal Life Cycles
What is a life cycle?
A life cycle is a series of stages a living thing goes through during its life. All plants and animals go through life cycles. It is helpful to use diagrams to show the stages, which often include starting as a seed, egg, or live birth, then growing up and reproducing. Life cycles repeat again and again.
Life cycle of an animal
Animals begin life either from an egg or as a baby that is born ready for life. Baby animals grow and change into adolescents and eventually become adults. Adult animals look for a mate to begin the life cycle all over again with new babies. Each type of animal has their own unique life cycle.
Life cycle of an animal
When babies are born or hatch from eggs, some look much like their parents, like kittens and horses.
Life cycle of an animal
Other baby animals look much different from their parents, like tadpoles which will turn into frogs.
Life cycle of an animal
Animals that change dramatically during their life cycle go through metamorphosis. For example, a mother butterfly lays eggs that hatch into baby caterpillars. As the caterpillar eats it grows bigger and bigger, and eventually it is ready to transform into a butterfly. The change takes place inside a chrysalis, where the caterpillar’s body changes into a butterfly. When the butterfly comes out of the chrysalis, it is ready to find a mate and lay eggs. Then the cycle can start all over again
