• Nymphs are always aquatic, while larvae are terrestrial.

• Nymphs undergo complete metamorphosis, while larvae undergo incomplete metamorphosis.

What is the first stage of complete metamorphosis?

• Egg

Illustrate the life cycle of a frog and compare it to that of a butterfly.

• Frog: egg → tadpole → tadpole with legs → adult frog; Butterfly: egg → caterpillar → chrysalis → adult butterfly.

• Frog: egg → tadpole → adult frog; Butterfly: egg → chrysalis → adult frog.

• Frog: egg → adult frog; Butterfly: egg → caterpillar → adult butterfly.

• Frog: egg → caterpillar → chrysalis → adult frog; Butterfly: egg → tadpole → adult butterfly.
