Resource competition

Resource competition occurs when different organisms or groups vie for the same limited resource, such as food, water, space, or nutrients. Because resources are finite, the more an organism or group uses, the less is available for others, leading to a struggle for survival or growth. This competition influences how species coexist and evolve, often promoting adaptations that help reduce overlap or improve resource efficiency. It plays a fundamental role in shaping ecosystems and the survival strategies of living things, ensuring that resources are shared based on availability and competitive ability.
