The simultaneous demand between two or more species-populations for a resource that is not abundant enough to support all of them at the sizes they would attain in the absence of the other species-populations.
competition and predation
Competition coefficients measure the effect of one species on another competing species.
Competition also can be modeled by examining resources rather than population growth equations.
The environment somehow must be limiting.
Predation,parasitism,mutualism,commensalism, and competition.
weeds would be one example.
it is spatial or temporal characteristics of organisms that have changed because of competition.
Relate to the size of one species- population to the other species.
Competition occurs when organisms of the same or different species attempt to use an ecological resource in the same place at the same time.
below the isocline of a population increases. above the iscline of a population in decerasing.
The open ocean is one of the largest ecological niches where organisms can live without intense competition due to its vastness and relatively low levels of nutrients. Deep sea environments at extreme depths and extreme temperatures can also provide habitats with minimal competition.
The number of individuals that can live in an ecological niche is dependent on factors such as resource availability, competition, and environmental conditions. As the competition for resources increases, the number of individuals that can occupy a niche may decrease. Each species adapts to its niche to maximize its chances of survival and reproduction within the specific ecological conditions.
