Answer:

Fish - fish life cycle starts with an egg. The egg hatches into what is called a yolk sac fry - a larval stage where the fish has an attached yolk that provides it with nourishment for its first week or two. ... Once the fish matures and can reproduce and lay eggs, it becomes an adult.

Frog - Life cycle of a frog consists of three stages: egg, larva, and adult. As the frog grows, it moves through these stages in a process known as metamorphosis. ... During metamorphosis, two hormones, prolactin and thyroxine, control the transformation from egg to larva to adult.

Insect - A life cycle is the series of changes an animal goes through during its life. ... The insect lives as an egg, larva (LAR- vuh), pupa (PYOO-puh), and an adult. Others have a three-stage life cycle. The insect is born as an egg, hatches as a nymph (NIMF), and changes into an adult.

Bird - While the hatchling is growing in the nest and being fed by its parents we call it a nestling. ... An adult bird attracts a mate, builds a nest and raises young to start the cycle all over again. Some birds migrate or travel long distances as part of their life cycle. Other birds stay in one area throughout the seasons.

Hope this helps you !
