Give Reasons :In animals showing external fertilization, the number of gametes produced is very large
Dear Student,
Organisms exhibiting external fertilisation releases more number of gametes into the surrounding to increase the chance of fertilisation. Because the fertilisation is external there is less possibility of fusion of gametes in the outside environment and if somehow fertilisation carried out successfully there will be chances that the externally fertilised eggs and young ones are at greater risk from predators. So, to ensure the chances of survival, these organisms releases large number of gametes to the surrounding.
Regards
