Resource scarcity creates competition among organisms for limited resources such as food, water, and shelter. This competition is driven by the need to survive and reproduce in an environment with limited resources available. Organisms that are better adapted to access or utilize these limited resources have a higher chance of survival and passing on their traits to the next generation, while those that are less able to compete may struggle to survive and reproduce. Therefore, the concept of resource scarcity drives competition, which ultimately determines the survival and success of organisms.
