Lifecycles

We have been learning about Lifecycles. So far, we have learnt the lifecycle of a frog and a butterfly.
A frog's lifecycle goes like this....

Egg
Tadpole
The Tadpole grows back legs
Then the Tadpole grows front legs
The Tadpole grows lungs so it can go up for air out of the water
The Tadpoles tail gets shorter and shorter until there is no tail left.
Then it becomes an Adult Frog
Then the Adult Frog lays eggs.

We know that lifecycles go around and around and around, they always start again.
