-A keystone species is a plant or animal that plays a unique and crucial role in the way an ecosystem
functions.
-Without keystone the ecosystem would be dramatically different or cease to exist altogether.
-Large compared to the species' prevalence in the habitat.
-Few predators can control the distribution and population of large numbers of prey species.
-The deer, rabbits, and bird species in the ecosystem are at least partly controlled by the presence of the mountain lion.
-A keystone species' disappearance would start a domino effect.
-The keystone species' disappearance could affect other species that rely on it for survival.
-The ecosystem can't support an unlimited # of animals, and the deer soon complete with each other for food and water resources.
-Without the keystone species, new plants or animals could also come into the habitat and push out the native species.
-With the sea stars gone, mussels took over the area and crowded out other species. Sea stars are also the keystone species.
-Pacific Northwest are mammals feed on sea urchins, controlling their population.
-Kepl, or giant seaweed is a major source of food and shelter for the ecosystem.
-Some species of crabs, snails, and geese depend on kelp for food.
Without sea otters to control the urchin population the entire ecosystem would collapse.
-If an acacia tree grown to a height of several feet, elephants area able to knock over the tree and up root it.
-Foundation species play a major role in creating or maintaining a habitat that supports other species.
-An umbrella species is a large animal or other organism on which many other species depend.
-Protection of umbrella species of thought to automatically protect a host of other species.
-An indicator species is a plant or animal that is very sensitive to environmental changes in its ecosystem.
