Detailed explanation-1: -As the chance of fertilization is nature dependant i.e it depends on the movement of water for the sperm to come in contact with the egg. Thus the fish and frog produce a huge number of eggs each year to overcome the chance factor(sperm to come in contact with egg) and produce offsprings.
Detailed explanation-2: -Why do frogs lay eggs in a very large amount? The odds of a tadpole’s survival are very low-nearly all of them die. Females therefore lay a large number of eggs to better the chance of having one or two surviving offspring.
Detailed explanation-3: -Fish and amphibians produce a lot of eggs when reproducing because they are fertilized externally; the large amount of eggs laid acts almost like an insurance policy to increase the chances that some will survive. A female fish or amphibian will typically release eggs in the water where males can then fertilize them.
Detailed explanation-4: -Both fishes and frogs reproduce by means of external fertilization. The female releases the egg in water and the male also releases the sperm in water. The sperm and egg then move close to each other by means of changes in turbulence in water and finally fuse to produce the offspring.
