Question

What are some examples of keystone species?

Answer 1

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.

Explanation:

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.
