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 adult. 
• 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 period 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.
