Oviparity is a reproductive strategy where animals lay eggs that develop and hatch outside the mother's body. This method is common in many species, including birds, reptiles, amphibians, and fish. The eggs contain all the nutrients needed for the developing embryo, allowing it to grow until it is ready to hatch. In oviparous species, the environment plays a crucial role in the survival of the eggs. Factors such as temperature, humidity, and protection from predators can significantly impact the success of the eggs. Examples of oviparous animals include chickens, turtles, and frogs.
