Answer 2

Internal fertilization is the process of fertilization that occurs inside the body of an individual. It occurs mostly in land animals. For internal fertilization to occur there needs to be a method for the introduction of male sperms into the female reproductive tract. Different animals have different methods of transferring the sperms. For eg., in mammals, reptiles, and some fish, this is done by copulation. In birds, this is done by the cloacal kiss.
