Hope this will help:

Metamorphosis is a process by which an organism gradually changes into a completely different one. For eg; a butterfly is developed from a larva through metamorphosis in a period of time.

The changes that a tadpole undergoes to develop into a frog are:

1. Eggs

2. Embryo

3. External gills develop for breathing.

4. The tadpole's tail keeps growing.

5. It's hindlegs develop.

6. Front legs appear.

7. Tail becomes shorter.

8. It changes into 'young frog' or 'froglet'.

9. It finally becomes an adult frog.
