Competition.
If the competition occurs between individuals of the same species it is called intraspecific competition.
If the competition is between individuals of different species it is called interspecific competition.
This concept is called competitive exclusion and often one or the other organism will adapt into a new way of making a living. See Darwin's finches.
natural occurrences
Just competition.
Competition: intraspecifically (between members of the same species) or interspecifically (between members of different species).
Survival of the fitest
We know that organisms that must struggle to survive in a habitat with limited resources will be in competition to do so.
The struggle between orginisms for limited resource is called competiton
Survival of the fitest
Competition: intraspecifically (between members of the same species) or interspecifically (between members of different species).
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
competition; is the struggle between species for the limited resources in a habitat.
Competition
Competition occurs when organisms existing at the same time and in the same place struggle for the same limited resources. This is one of the three major types of interactions among organisms, the other two being predation and symbiosis.
Quite true, but you can refine the definition ecologically speaking and say this is also a form of competitive exclusion.
