The butterfly's eggs are hatched into caterpillars. When the caterpillar is full-grown and stops eating, after a while and makes a cover for itself, it becomes a pupa. Cockroaches do not hatch into larva. The young ones that come out of the eggs look like adult insects but are smaller. They are called nymphs. The young ones which hatch out of frog's eggs are called tadpoles. Tadpoles do not have legs. They have fins that help them to swim around, looking for food. Dogs are mammals which give birth to their young ones called as a puppy. Birds reproduce by laying eggs that can hatch into chicks. Column A Column B 1.Butterfly e. pupa 2.Cockroach a.nymph 3.

Reproduction is the ability by which living beings produce the young ones of their own kind. For example, a cow produces a calf and a dog produces puppies. Birds lay eggs out of which baby birds hatch out.

Incubation is the period in which the mother or father bird often warms and protects the eggs until they hatch into young birds called chicks.

Animals that give birth to their young ones are called mammals. For example, cats, dogs, human beings, etc. In mammals, the young ones develop inside the body of the mother. They feed milk to their young ones.

Nymphs are the young ones of insects that come out of the eggs and look like the adult insects. They are part of the life cycle of insects. For example, insects like cockroaches and grasshoppers hatch eggs into nymphs.
