Question

The viviparous animals can produce a lesser number of young ones per litter when compared to the oviparous ones. Give reasons.​

Answer 1

$\bullet$ In viviparous animals, the development of the embryo takes place inside the womb of the mother.​
$\bullet$ 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.​
$\bullet$ But in oviparous animals, the development of the embryo takes place outside the mother body in the external environment.​
$\bullet$ There are many stages for hatching between these time periods; many eggs are broken or do not incubate well.​
$\bullet$ So, a large number of offspring are produced per litter.​
