Solution

External fertilization:
When the fertilization occurs outside the body of the female, it is termed external fertilization.
External fertilization is most common in aquatic habitats, where both eggs and sperm are released into the water.
Fertilization can begin once the sperm reaches the egg.
Fish, frogs and starfish reproduce externally by releasing their eggs into the water and releasing the sperms over the secreted eggs.
