Which species are keystones?
D. Sea otters, lions, and sea stars are also considered important keystone species. Answer to Question #2. C is correct. While kelp forests are a required habitat for many nearshore species, sea otters are considered the keystone species in most ecosystems with kelp forests because they consume sea urchins, which would otherwise decimate ...
Why are keystone species important?
Keystone species are also critical for the overall structure and function of an ecosystem, and influence which other types of plants and animals make up that ecosystem. Thus, in the absence of a keystone species, many ecosystems would fail to exist. A common example of keystone species in the context of conservation biology is ...
Why are sea otters considered a keystone species?
The sea otter (shown below) is considered a keystone species as their consumption of sea urchins, preventing the destruction of kelp forests caused by the sea urchin population. Kelp forests are a critical habitat for many species in nearshore ecosystems. In the absence of sea otters, sea urchins feed on the nearshore kelp forests, thereby disrupting these nearshore ecosystems. However, when sea otters are present, their consumption of sea urchins restricts the sea urchin population to smaller organisms confined to protective crevices. Thus, the sea otter protects the kelp forests by reducing the local sea urchin population.
What are some examples of keystone species?
