Read the passage. Answer the questions that follow.
Most animals including fish, mammals, reptiles and birds have very simple life
cycles. They are born either alive from their mother or get hatched from eggs. They
grow up. These animals have three stages—before birth, young and adult.
Amphibians undergo a metamorphosis or a big change. They are born either alive
from their mother or are hatched from eggs. They spend their childhood under
water, breathing with gills. They grow into adults and move to the land, breathing
with their lungs.
Insects, such as butterflies, have four stages in their life cycle—egg or the unborn
stage; larva or the young stage when most of the feeding is done and the insect
usually looks like a worm. Pupa is the inactive or no feeding stage between larva
and adult stages. This is followed by the adult stage.
Dragonflies, grasshoppers and cockroaches are insects that go through an
incomplete metamorphosis. They do not have a pupal form and have three stages
in their life cycle, namely, egg; nymph or young stage and adult stage.
