Hey mate!!!

Here is ur ans...

Life cycle of butterfly:

The female butterfly lays the eggs.The eggs laid are actually zygotes.The eggs are fertilized within the body of the mother(female)with the sperms from father(male).Fertilization in butterfly is internal..

Eggs(zygotes)➡larva➡pupa➡adult.

Metamorphosis in frogs:

Fertilization in frogs takes place in water.

Fertilization in frog is external(outside the body of the mother(i.e)lays eggs).

The fertilized eggs are enclosed by a thick jelly.

The whole mass of zygotes in a jelly is called spawn..

Note:

In tadpoles,secretion of hormone thyroxine initiates metamorphosis..
