Which of the following is the underlining Principle in the adoption of biological control of pests?

The underlying principle in the adoption of biological control of pests is the predator-prey relationship in ecological community. Biological control involves the use of natural enemies such as predators, parasites, and pathogens to manage pest populations. These natural enemies attack and feed on the pest species, ultimately reducing their population to an acceptable level. The success of biological control depends on understanding the complex interactions between the target pest, the natural enemy, and the environment. By utilizing the natural enemies of pests, biological control can effectively manage pest populations without the use of harmful chemicals, which can negatively impact the environment and human health.
