Final answer:
The result of two organisms trying to use the same resources is competition, which may lead to one species dominating over the other unless resource partitioning occurs, allowing both to coexist.
Step-by-step explanation:
When two organisms attempt to utilize the same resources, the result is competition. This is a fundamental concept in ecology where different species (interspecific competition) or individuals within the same species (intraspecific competition) strive for limited resources such as food, water, or space within the same environment. The competitive exclusion principle asserts that two species cannot coexist in the same habitat if they compete for all the same resources. For coexistence to be feasible, they may evolve different specializations or engage in resource partitioning to minimize direct competition and occupy different microniches.
