Answer:

Explanation:

Organisms that take part in such process produce large number of gametes because:

(i) In external fertilization, there is a great chance that the sperm and the eggs released by the organisms can be affected by factors present in the environment like desiccation ,predators, etc. So, to make up for the high fatality rate of the gametes, the organism produces a lot of gametes.

(ii) Producing large number of gametes increase the chance for at least some eggs and sperms to meet in the environment ensuring that at least a stable number of offspring are able to survive and carry on.

Hope it helps :)
