Which statement about biological control methods is true?

Biological control methods focus on leveraging natural predators, parasites, or pathogens to manage pest populations. Modifying the environment to enhance the presence of natural enemies is indeed a recommended practice within biological control. This can involve creating conditions that are favorable for these beneficial organisms, thereby allowing them to thrive and effectively reduce pest populations.

On the other hand, the reliance on chemical pesticides contradicts the fundamental principles of biological control, which aim to minimize chemical interventions. Furthermore, by definition, biological control methods do involve natural pest enemies, and they can often be effective in a variety of environments, not just controlled settings. Enhancing environmental conditions supports the overall ecosystem, promoting a balance that can reduce pest-related issues over time.
