A biological community is made up of many plants and animals, but certain members
are considered keystone species. The mountain lion, for example, can control the
populations of several prey species within its habitat. Scavengers such as vultures also
adjust their location and activities due to the movements of the mountain lion. Were
mountain lions to disappear, many other species would be impacted. There are many
types of keystone species, and they are present in each biological community. The bee,
for example, is vital to the survival of trees, which many other species depend upon.
