The term for the balance of nature in ecological systems is ecological balance. This concept refers to the stable relationships among various organisms within a habitat, which include predator-prey interactions, competition for resources, and mutualisms. Maintaining ecological balance is essential for the health of ecosystems, ensuring that biodiversity and ecosystem services are preserved. Disruptions, such as habitat destruction, pollution, or the introduction of invasive species, can lead to ecological instability, adversely affecting species survival and ecosystem resilience.
