What do organisms experience because of growing population

Competition and research partitioning

The competitive exclusion principle states that when two organisms attempt to fill the same niche, one will exclude the other from the ecosystem. Research partitioning is an adaptive evolution that when species are have similar preys, they compete with each other and one species is deemed to extinct in the process however if two species are of different preys, then they can exist with one another. To exist with one another, organisms belonging to a same species either compete for the resources or divide it amongst themselves. This concept is important because it helps in diversified ecology, where animals and plants of the same species co-exist and creates a beauty with nature.
