$\huge\red{\mid{\fbox{\tt{❥answer࿐}}}\mid}$

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.

There are three ways in which internal fertilization produces offsprings:

• Oviparity

• Ovoviviparity

• Viviparity

Answer 2

Answer:

• Internal fertilization is the union of an egg and sperm cell during sexual reproduction inside the female body. Following fertilization, the embryos are laid as eggs in oviparous organisms, or continue to develop inside the reproductive tract of the mother to be born later as live young in viviparous organisms.
