What is Viviparity?
Viviparity is the process of reproduction in which the embryo develops inside the mother's body, and it is nourished by the mother. This is opposed to oviparity, which is the process of reproduction in which the embryo develops outside the mother's body and is nourished by the egg yolk. Viviparous animals include mammals and some reptiles.
How Does Viviparity Work?
Viviparous animals use a system of placentation to nourish their embryos. A placenta is an organ that connects the mother's body to the embryo. It is composed of a network of blood vessels that connect the two, allowing the mother's nutrients to pass through the placenta to the fetus. This allows the fetus to obtain oxygen, food, and other necessities from the mother.
Do Viviparous Animals Have Different Nutritional Needs?
Yes. Viviparous animals have different nutritional needs than oviparous animals. Viviparous animals require a greater amount of nutrients, as they need to provide nutrition to the developing embryo. They also require extra vitamins and minerals, such as calcium and iron, as these are essential for healthy fetal development.
Where Do Viviparous Animal Embryos Get Their Food From?
Viviparous animal embryos get their food from the mother. The mother's blood passes through the placenta, delivering nutrients to the embryo. This provides the embryo with the energy and nutrients it needs to grow and develop.
What Are the Benefits of Viviparity?
Viviparity has several advantages over oviparity. Firstly, it allows the mother to provide nutrition to her offspring, ensuring that they receive all the nutrients they need to develop. Additionally, it allows the mother to protect the embryo from external threats, such as predators or extreme temperatures. Finally, viviparity ensures that the mother is able to give birth to live young, which is beneficial for the species.
