  4. Interspecific competition - Wikipedia

    en.wikipedia.org/wiki/Interspecific_competition

    The two species share the same ecological niche, and are thus in competition with each other. Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resources in an ecosystem (e.g. food or living space). This can be contrasted with mutualism, a type of symbiosis.
