What when more than one organism or population fights over the same limited resource it leads to?

When more than one organism or population competes for the same limited resource, it can lead to increased competition, which may result in various outcomes such as resource depletion, shifts in population dynamics, or changes in behavior. This competition can drive natural selection, favoring individuals that are better adapted to exploit the resource or that can evade competitors. Ultimately, it may lead to the exclusion of less competitive species or the evolution of strategies that reduce direct competition, such as niche differentiation.
