The flow chart illustrates the development of a frog from egg during its life cycle.

Overall, it is clear that there are six distinct stages illustrated in the process, commencing with producing eggs in the water and ending with the development of a mature frog.

The first stage is when the eggs, shown as frogspawn, float on the surface of the lake. The next step after this is the emergence of the small tadpole after the frogspawn hatches. At this point in the cycle , the small tadpole has a small body with a long tail. Over time , the tadpole grows and its body becomes bigger while the tail becomes longer. At the same time , the legs begin to form so as to prepare the tadpole’s future life on land. Eventually , the tadpole starts to grow into a young frog with a wider mouth, a shorter tail and larger legs although it continues to live in the water. Gradually , the frog becomes mature, ready to leave the water and moves onto the land. When being on land, it starts to breathe air and loses the tail. The final stage of the cycle is when the adult frog finds a mate in order to lay eggs. Having completed all these steps , the lifecycle will then begin again.
