Which definition describes biological control in the context of pest management?

Biological control in pest management refers to the strategic use of natural enemies—such as predators, parasites, or pathogens—to regulate pest populations. The deliberate introduction of these organisms into new regions aims to provide a sustainable and environmentally friendly alternative to chemical pesticides. This approach leverages the natural relationships within ecosystems to achieve pest control, ultimately reducing the reliance on synthetic chemicals and minimizing ecological disruption.

The other options involve methods that do not fall under biological control. Chemical pesticides specifically rely on synthetic chemicals to kill pests, whereas biological control emphasizes natural interactions. Habitat destruction aims to eliminate pests by altering their environment, but it does not involve using natural enemies to control pest populations. Lastly, genetic engineering focuses on modifying organisms at the genetic level to control pests, which is fundamentally different from utilizing natural ecological interactions observed in biological control.
