What is the difference between viviparous and oviparous animals?
Answer Details
The difference between viviparous and oviparous animals is how they give birth to their offspring.
Viviparous animals give birth to live young that have developed inside the mother's body. In this case, the embryos receive nutrients from the mother through a placenta or similar structure. Examples of viviparous animals include most mammals, including humans, as well as some reptiles, such as certain species of snakes and lizards.
Oviparous animals, on the other hand, lay eggs that hatch outside the mother's body. The eggs are typically fertilized before being laid, and the embryos develop inside the eggs. The eggs are either laid in a protected environment or are actively guarded by the parents until they hatch. Examples of oviparous animals include birds, reptiles, amphibians, and some insects.
Therefore, the correct option is: "Laying and brooding of eggs" is the difference between viviparous and oviparous animals.
