Solution

In viviparous animals, the development of the embryo takes place inside the womb of the mother.​
The structure of the body results in the production of young ones. It is developed inside the uterus of the mother. So, fewer offspring are produced per litter.​
But in oviparous animals, the development of the embryo takes place outside the mother body in the external environment.​
There are many stages for hatching between these time periods; many eggs are broken or do not incubate well.​
So, a large number of offspring are produced per litter.​
