The follow chart gives information about the development of frog from eggs to mature frog.
As can be seen from the first step, the femal frogs lay their eggs under water in form clusters of eggs.
Looking from an overal respectively, the process of amphibian is divided into nice steps, beginning with their’s eggs, and ending with mature frog. Then the embryo inside of eggs are developed to tadpoles, which are based on water-plant. Next step, the tadpoles are extended the gills which allow them can move under water. Afterwards, the tail is grown as long as body size of the tadpole.
In next two steps, step 6 and step 7 show that the behind legs of frogs appear and they live based on the nutrion from their tails. Then the frogs developt front legs and their tails become short as well in step 8 and 9. After removing the tail, it becomes a young frog and then they continue to grow to mature frogs. The process repeats when the adult amphibians product their eggs.
