What is true about biological control methods?

Biological control methods involve the use of living organisms, such as predators, parasites, or pathogens, to manage pest populations. The statement that modifying the environment can enhance natural enemies is correct because by altering the habitat or conditions in which pests and their natural enemies exist, it is possible to promote and sustain the populations of these beneficial organisms. For example, planting certain types of vegetation can provide shelter and food for beneficial insects, thereby increasing their effectiveness in controlling pest populations.

This approach emphasizes the use of ecological principles to foster a balance between pests and their natural enemies, rather than relying solely on chemicals. In contrast to chemical pesticides, which can have harmful effects on the environment and non-target organisms, enhancing natural enemies through environmental modifications is a more sustainable pest management strategy.
