Detailed explanation-1: -As the frog develops into an adult, it will begin to eat insects rather than vegetation. It can take up to four years before the frog becomes fully mature. Once it is, the frog can then lay eggs or fertilize them, and the life cycle of a frog can start all over again!

Detailed explanation-4: -If we consider the life cycle of a frog, there are three stages. Eggs of a frog develop into a larva (tadpole) and later become an adult frog. These drastic changes in appearance and stages are not as long as human growth. The changes in the stages from a larva to an adult are known as metamorphism.
Detailed explanation-5: -The third stage is the froglet stage. It grows lungs and legs. Its gills disappear. Its tail gets shorter until it disappears too.
