what is interior and exterior fertilization?

Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body. External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.

Examples of external fertilization are in plants like moss or algae, where the sperm and eggs meet outside of the parent's body and produce a zygote, which then grows into a mature plant. External fertilization in animals are usually in marine organisms, like sponges, because the sperm needs to swim in water to meet the egg.

What is reproduce and fertilization?

In sexual reproduction, two parents donate genes to their young, resulting in offspring with a mix of inherited genes. These genes are donated through a process called fertilization. There are two mechanisms by which fertilization can take place. The first is external (the eggs are fertilized outside of the body), and the second is internal (the eggs are fertilized within the female reproductive tract). While fertilization is necessary for organisms that reproduce sexually, individuals that reproduce asexually do so without the need for fertilization. These organisms produce genetically identical copies of themselves through the process of mitosis.

What Two advantages of external fertilization?

A large quantity of gametes can be fertilized at one time, possibly leading to a larger number of offspring. Furthermore, external fertilization ensures the wide dispersal of offspring (by the ocean currents), thus resulting in less competition for resources such as food and living space.
