Sea otters are an example of a keystone species because due to their feeding habits, kelp is allowed to flourish which leads to absorption of high amounts of CO_2, preservation of the organisms which rely on kelp for survival, as well as protecting coastlines. Keystone species are crucial species in an ecosystem. If they were to be removed from an ecosystem, there would a drastic impact on most of the species and the environment within that ecosystem.
