Question

why do female frogs lay hundred of eggs?

Answer 1

Since external fertilisation takes place, the chance of egg getting fertilised is less compared to internal fertilisation. To balance this, they lay hundreds of eggs.

Answer 2

Explanation:

Animals like frogs and fish lay hundreds of eggs and release millions of sperms. ... This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs.
