Question

Quizplus · Accepted Answer

In external fertilization, the sperm and egg unite outside of the body, typically in water. This method is more common in aquatic organisms, where the eggs and sperm are released into the environment. Since the eggs and sperm are exposed to the environment, there is a higher risk of predation or environmental stress, which is offset by the production of large numbers of offspring. With so many offspring to care for, parents typically do not provide parental care beyond the initial investment of gametes. Therefore, external fertilization is generally associated with large numbers of offspring and low levels of parental care.
