Without the presence of sea otters, sea urchins would otherwise overgraze kelp beds, dramatically changing the marine community of which the urchins and otters are a part. For this reason, sea otters are considered _____________. Select one: a. A parasite b. A keystone species c. A predator d. An indicator species
c or b i think ?
