What is a characteristic of biological control?

A characteristic of biological control is that it is never complete. This is due to the nature of biological control methods, which typically involve the use of natural predators, parasites, or pathogens to manage pest populations. These biological agents do not eliminate pests entirely; rather, they work to suppress their populations to acceptable levels. The dynamics of ecosystems mean that biological agents can be affected by various environmental factors and other organisms, leading to fluctuating levels of pest control.

In contrast to other control methods, such as chemical control, biological control relies on the balance of natural processes, making complete eradication of pests unlikely. This non-complete nature allows for a more sustainable approach to pest management, as it mitigates the risks associated with chemical usage and fosters ecological balance.

Understanding this concept helps to clarify why biological control is an important component of integrated pest management strategies, focusing on sustainable and environmentally friendly practices.
