Which of the following is a characteristic of biological control?

Biological control refers to a pest management strategy that involves the use of living organisms to suppress pest populations, particularly through the introduction of natural predators, parasitoids, or pathogens. This method relies on the natural ecological relationships and interactions within ecosystems, wherein natural enemies can help keep pest populations in check.

By introducing natural predators, such as ladybugs or parasitic wasps, growers can enhance biological control, thereby reducing reliance on synthetic chemicals and minimizing environmental impacts associated with pesticide application. This approach is sustainable and aligns with integrated pest management principles, making it a critical component of modern agricultural practices aimed at maintaining ecological balance and promoting health in ecosystems.

Other methods, such as the use of synthetic chemicals, application of heat, or manipulation of pH levels, focus on direct interventions that can have varying effects on pests but do not leverage ecological interactions as biological control does.
