Answer:
The external fertilization in organisms like frog, has indirect development....
The frogs lay eggs, that are without any covering, In the open water where the male gametes fuse the eggs....
Not all the eggs fuses but those which come in contact with the male gametes and get the desirable condition and environment fuse and develop into a new individual......
There is no role of the parent in its development...
Internal fertilization in organisms like humans, have direct development..
The female egg gets fused by male sperm to form zygote and then it grows and develops inside the mother's body...
It gets all the nutrients from the mother's body....
It cannot survive independently and hence is direct....

Answer:
External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body.[1] It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism.[2] External fertilization typically occurs in water or a moist area to facilitate the movement of sperm to the egg.[3] The release of eggs and sperm into the water is known as spawning.
