Question

Why is development of embryo takes place inside the body of animals in case of oviparous animals ?
​

Answer 1

Answer:

Oviparous animals are the animals that lay eggs.

Viviparous animals give birth to the living offspring that develop within the mother's body (as in the case of most of the mammals).

Ovo-viviparous give birth to the young ones in eggs which are hatched within the female body (as in some reptiles and fishes).

Herbivorous animals are those that feed exclusively on vegetable food.

Answer 2

Answer:

In oviparous animals, fertilization takes place internally but embryo development takes place externally. ... Once the fetus is matured, the egg hatches.
