Thereof, why are polar bears important to the ecosystem?
As an apex predator at the top of the food web, polar bears can signal that there are problems in the Arctic marine ecosystem. They are likely to be among the most significantly affected species as the Arctic warms and sea ice melts.
Similarly, why is the Arctic fox a keystone species? The Arctic fox is a keystone species because it is the main food source of polar bears, wolves, and kittiwakes.
Regarding this, why are keystone species often predators?
A keystone species is often, but not always, a predator. Just a few predators can control the distribution and population of large numbers of prey species. The entire concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.
What are keystone species and why are they important?
Keystone species are integral to their specific ecosystem and habitat, as they play a role deemed vital to the existence of the species which share their home. They define an entire ecosystem. Without its keystone species, ecosystems would be dramatically different or cease to exist altogether.
