Question

What is the negative side of external fertilisation?

Answer 1

External fertilization is a male organism’s sperm fertilizing a female organism’s egg outside of the female’s body.Internal fertilization, on the other hand, is the occurrence of internal insemination as the mode of combining sperm and egg.External fertilization occurs in water or a moist area because it gives the sperm external mobility to get to the egg.While in the water, the sperm and ova can shed simultaneously to fertilize the egg.The release of eggs and sperm into the water is known as spawning.When females spawn, they release a batch of eggs into a spot of their choice or just into the water, as in bottom dwelling or sessile species and all of the males start to release sperm that are in close proximity. Within vertebrates, it is the amphibians and fish that use external fertilization.
