    The fish and frog lay eggs in hundreds and millions of sperm because all the eggs do not get fertilized and developd into an new individuals. This is because the eggs and sperms get exposed to water movement , wind rainfall also , there are other animals in the pond which may feed on eggs . Thus production of large number of eggs and sperm is necessary to ensure fertilisation of at least at a few of them.??
