this occurs when 2 or more organisms or populations in a community rely or need similar limiting resources.

The occurrence when two or more organisms or populations in a community rely on or need similar limiting resources is called competition. Competition happens because the resources required, such as food, water, space, or light, are limited, leading these organisms or populations to compete for them. This interaction can happen within the same species, called intraspecific competition , or between different species, called interspecific competition. Competition affects the fitness of the organisms involved since the presence of one reduces the availability of the resource for the other.
