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 whereas 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.
