Question

What conditions must be established before a researcher candefinitively state that two species are competing for a resource? Is establishing that two speciesoverlap in their use of a resource a sufficient condition to determine that interspecificcompetition is occurring? Explain your answer.

Since you are referring to two species, this is a type ofinter-specific competition (as opposed to an intra-specific forpopulations of the same species).
If there's an overlap in a resource, it's enough to showinterspecific competition; By the competitive exclusion principle,species are in competition when its NICHE is at risk. If theresource is important for both species for survival andreproduction ( also maintaining its position in the ecosystem),then it signifies this type of competition.
