What dramatically changes when starfish are removed from the stimulated system?
Ans. (B) The Mussel population increases in size
Reason
Starfish is an aquatic echinoderm that feed on Mussels. Stimulated ecosystem is a type of artificial ecosystem which function exactly like the natural one. The removal of starfish from this aquatic ecosystem can result in increase in population of mussels. The number of prey species increases when the predators are removed from the ecosystem.
