The diagram describes the different stages in the life cycle of a frog, an amphibian. Overall, the life cycle consists of 8 stages, opening with mating and ending with the development into adult frogs. The cycle begins with mating between male and female adult frogs in the ground level. The female frogs subsequently lay a large number of eggs on the water, each having an embryo inside. In the next step, these frogspawn hatches from the egg and little tadpoles emerge from them which cling to water plants. Gradually these tadpoles grow bigger and start to form various limbs.
The following stage is the transformation of the tadpoles into young frogs. Their tails start to become longer than before and the limbs such as gills grow considerably. In the next stage, the tadpoles start to change as their figure becomes larger in size, and their hind legs appear. Next, their front legs emerge and during this stage, pulmonary breathing also commences. Thus, their journey on water ends and ground life begins. Afterward, their tails begin to shorten which disappear in the succeeding stage. Finally, the young frogs turn into adult frogs that are now ready for mating again.
