Question

Question 18: Why are offspring of oviparous animals at a greater risk as compared to offspring of viviparous animals?

Class 12 - Biology - Reproduction in Organisms Page 18

Answer 1

the offsprings are protected in viviparous animals as they are inside thier parents while offsprings of oviparous are laid outside in eggs
exposed to all the environmental conditions.

Answer 2

Hey there,

★We know that in viviparous organisms development of zygote takes place inside the female parent body.

★So , the organisms are provided well with nutrients from female parent.

★As they are inside the female parent so they dun have to suffer from any kind of environmental changes.

★In oviparous animals , development of zygote takes place outside the female parent.

★Outside organisms are not protected by predators.

★They have to suffer from environment changes and that may even lead to the decrease in thier Number.

Thanks!
