because their is difference between the eggs size

Yogita Ingle 7 years ago

1) External fertilization occurs in fish and frog.

2) The females lays a vast number of eggs in water & males releases some millions of sperms on to them.

3) Eggs may be carried to a long distance by water currents or they may be eaten by predators.

4) So,fertilization is a chance factor & controlled by nature.

Hence it is inevitable to produce a vast number of eggs by fish & frog.
