IELTS PART 1 - The life cycle of frog
The diagram presents the frog's metamorphosis which is a breakdown into six different phases. It is important to bear in mind that the phases of the frog' live is enormously different from eggs to the adult frog.
To begin with, the first process initiates when the female frogs lays their eggs on the surface of the lake. Afterwards, the frogspawns grows into tadpole which is the embryo with a tiny body and a long tail. The next development stage is that front legs appear to be true in the tadpole. After taking many times, the long-tail embryo have a pulmonary breathing to help them to respire in out of the water and the two legs in the back of frogs was grown.
Then the tadpole frog grows become adult frog with changing in their tails getting shorter. In addition, the adult frog become much bigger than the previous one. More broadly, in this phase, the adult frog become strong enough to live in the land.
