The diagram explains the life cycle of a frog.

Generally, adult frog comes from eggs and realizes several steps.

To begin, entire group process starts from eggs of a frog changed become embryo and become tadpoles that are having three sizes (short, middle and long). Then, it changed to be front legs break through before it starts to become of pulmonary breathing. All of these processes occur in the water.

After it undergo the process in the water, a frog is going to land and it realize process to become tadpole frog before it changed become adult frog. After that, we can be seen many frogs can live in the land.

Your essay is really specific. I think it's good.
However, there are some places that you can improve.
1. Try to use "first" "second" "third"..."finally"
2. You use too many "it". "it" who? it's really ambiguity! You should use the concrete words.

The suggestions mentioned above, you can try.
Good Luck !! ^^

... Good introduction :)


.... this needs improvement;
Overall, there are seven stages in the life cycle of a frog which begins with eggs and ends up with an adult frog.
This is your overview and there you need to give an overall picture of your diagram. So, tell something more meaningful in the intro for the reader to get an idea of what you are going to talk in detail in the forthcoming paras.
