Detailed explanation-1: -Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. Internal fertilization enhances the fertilization of eggs by a specific male.
Detailed explanation-2: -Internal fertilization refers to the process of syngamy occurring within an organism’s bod. Eggs are generated inside the female body where they fuse with the male gamete. The male gamete in species with internal fertilization is motile and must approach the egg in order to combine with it.
Detailed explanation-3: -External fertilization is primitve and internal fertilization is advance. External fertilization is not advanced because it occurs outside the body of the organisms, mostly in water in most aquatic organisms so that a large number of gametes are wasted.
