Answer:

Explanation:

1) Fish and frogs are oviparous animals.

2) Though these animals lay hundreds of eggs and release millions of sperms, all the eggs do not get fertilized and develop into new individual. 3) This is because the eggs and sperms get exposed to water movement, wind and rainfall.

4) Also there are other animals in the pond, rivers which may feed on eggs.

5) Thus production of large number of sperms and eggs is necessary.
