Answer 2

Answer:

Animals show different methods of production of young ones. Oviparous and viviparous are such two methods. The main difference between oviparous and viviparous animals is:

The oviparous animals do not undergo any embryonic development inside the mother

Viviparous animals develop into a young animal inside the mother.

This means oviparous animals lay eggs. These eggs develop and hatch into young individuals.

In contrast, viviparous animals are born as live young individuals. Therefore, they do not lay eggs.

Birds, reptiles, amphibians, most fish, insects, mollusks, arachnids, and monotremes are oviparous animals.

Most mammals are viviparous animals.
