What term describes a symbiotic relationship in which two or more populations achieve results they cannot accomplish alone?

The term that describes a symbiotic relationship in which two or more populations achieve results they cannot accomplish alone is synergism. In a synergistic relationship, the interaction between the organisms leads to a combined effect that is greater than the sum of their individual effects. This collaboration enables both populations to benefit, often enhancing their survival, growth, or reproductive success in ways that they would not be able to achieve independently.

Understanding synergism is essential in various fields, including microbiology and ecology, as it highlights the importance of cooperative interactions in ecosystems. For instance, certain bacteria may work together to break down complex organic compounds more efficiently than they could when acting alone, showcasing how synergistic relationships can lead to greater resource utilization and ecological balance.
