The portion of the community involved in competition
Everything within the ecosystem
The portion involved in coevolution
The "living" portion of the ecosystem
A competition between two species that harms one and benefits the other
The particular space within an ecosystem occupied by a species
A process wherein two interacting species act as agents of natural selection on one another
A mechanism that results in death of one of the competing individuals
An interaction between two species that benefits both
They do not compete within the niche for the resources it provides
The niche is not necessarily the home of any of the species
Intraspecific competition will be detrimental to the species
No two species ever occupy exactly the same ecological niche within the same community
When there is competition between a predator and prey
Only when available resources are limited
When they attempt to use the same limited resources, particularly energy, nutrients, or space
When resources are partitioned
Loss of physical and behavioral adaptations
Population size reduction
Predator and prey relationships
