Well, it depends on the animal. Butterflies, for example, have between 4 or 5 stages in their life cycle. Frogs have around 3 or 4. Grasshoppers have 3. Humans have between 2 and 13.
yes
Ants have 4 stage life cycles.they hatch from eggs and become larva after that they turn into pupas and then emerge from them as ants.
It is Interphase.
That would be a frog they go from eggs to a tadpole to a tadpole with legs then to a frog .
