b) oviparous with external fertilisation.

Fertilisation that occurs outside the body of an organism is known as external fertilisation. It usually requires a water body for successful fertilisation.

  • It results in increased genetic variations.
  • It produces a larger number of offspring.
  • The gametes released can drift, and therefore it is easy to find mates.


The female releases the eggs into the water. The male also releases the sperms in the water to fertilize them. The larval life of the frogs is in water, whereas the adult life is on land.
