(02.04 MC) Pоllutiоn in аn оceаn ecosystem hаs caused a significant drop in sea otter population. Within a year, scientists monitoring the ecosystem note that the sea urchin population on which the otters feed has greatly increased. The prevalence of sea urchins has caused the kelp and algae populations on which the urchins feed to decrease. The scientists fear the urchins will also begin to overwhelm the ecosystem's fragile coral population. Which species is most likely the keystone species in the ecosystem?
