Question
Why are the offsprings of oviparous animal at a greater risk as compared to offsprings of viviparous organisms?
Solution
Oviparous animals are egg-layers. The eggs containing embryos are laid out of their body and are highly susceptible to environmental factors (temperature, moisture, etc.) and predators. Whereas, in viviparous animals, the embryo develops inside the body of a female and comes out as a young one. Hence offsprings of oviparous animals are at risk compared to a viviparous animal.
