The Diagram gives informations about frogs, specifically it explain the different stage of their life.
The cycle starts when one male specimen and one female specimen of frog mate. As a result the female specimen lays eggs that are technically called frogspawn. After about 7-10 days, the frogspawn hatch giving life to tadpoles. During the tadpole stage, they are going to feed by algae. After 6 weeks, the tadpoles that before used to move with their tale, now develop also two small back legs. Following 9 weeks, in addition to the tail and legs, it also has two small front legs. In the next stage, the tadpole starts the pulmonary breathing becoming a froglet. Then, the froglet lost its tail, meanwhile the legs grow up and it become a young frog. After 4 years, the young frog grows further into an adult.
During its life cycle , the frog pass the first stages of its life, from eggs to tadpole, living under water. When it turns into a froglet, it lives between water and land. Once it grows into young frog, it starts to live above all on the land.
