A keystone species if often, but not always, this type of species, because they can control the distribution and populations of large number of prey species.
Refers to the way in which an organism fits into an ecological community or ecosystem.
The native species
Without keystone species, new plants or animals could also come into the habitat and push out this species.
A plant or animal that plays a unique and crucial role in the way an ecosystem functions.
Example of keystone species
Deer, rabbits and bird species in the ecosystem are at least partly controlled by the presence of the mountain lion.
Example of domino effect
The population of deer or rabbits would explode without the presence of a predator.
The interaction between organisms are species in which both the species are harmed.
