Kelp forests provide critical sources of food and habitat for a variety of marine invertebrates, zooplankton, bivalves, and fish species. This makes kelp a species of their ecosystems. Sea otters, in turn, consume which feast on kelp. This makes sea otters a unique species because they maintain a stable population of kelp consumers and prevent the collapse of the entire ecosystem.
