Question

Write short notes on number of eggs or young ones produced by an oviparous and viviparous.

Answer 1

Oviparous animals

• Animals which lay eggs are called oviparous animals.
• They produce more number of eggs since the eggs are exposed to environmental conditions and predators.
• They have to pass through several developmental stages before becoming on *****.
• They face less chances of survival.
• Hence they produce more number of eggs to ensure continuation of battle.
• Further, the eggs are released from the parent and develop with the help of yolk stored in the egg.
• Parental care is not seen. Viviparous animals :
• Animals which give birth to young ones are called viviparous animals.
• One or few eggs are produced by the female since the mother has to undergo gestation ** and nurture the young ones in her womb until they are born.
• Reproduction cycle requires more time.
• But the embryo is protected from environmental conditions and predators.
• Chances of survival are very high.
• Therefore the number of eggs / young ones in a viviparous animal will be less as compared to an oviparous animal.
