Vedclass · Answer

(B) Organisms exhibiting external fertilization release a large number of gametes into the surrounding medium (water) to enhance the chances of syngamy. Since the gametes are released into an open environment,they are highly susceptible to predation,environmental hazards,and physical dispersal,which significantly reduces the probability of successful fusion between male and female gametes. Therefore,producing a vast number of gametes is an evolutionary strategy to ensure that at least some gametes successfully meet and fuse,thereby increasing the chances of fertilization and survival of the species. Examples include bony fishes and frogs.
