What does biological control rely on?

Biological control relies on the use of beneficial organisms to manage pest populations. This method involves introducing or enhancing the presence of natural predators, parasites, or pathogens that specifically target the pests, thereby reducing their numbers in a sustainable and environmentally friendly manner.

Using beneficial organisms can help maintain ecological balance and promote biodiversity. Unlike chemical pesticides, which might have harmful effects on non-target species and the environment, biological control focuses on leveraging the natural relationships within ecosystems. This approach not only aids in pest management but can also contribute to healthier ecosystems overall.

The other options do not align with the principles of biological control. While chemical pesticides are designed to eliminate pests directly, that is contrary to the concept of biological control. Similarly, removing pest habitats or creating mechanical barriers can be part of an integrated pest management strategy, but they do not constitute the biological methods that rely specifically on interactions among living organisms.
