Some other examples of competition include: ________ competition, where one species uses overt aggression to drive another species away from a resource; ________ competition occurs when one species simply uses the resource first, and by doing so, reduces the amount of resource available to a competitor species.
The total number of different species in a community is called species ________.
________ broadly applies to not only the number of different species, but also the relative abundance of each species in the community.
