Final answer:
Biotechnology can decrease the use of pesticides by genetically modifying crops, introducing natural predators of pests, and enhancing crop immunity.
Step-by-step explanation:
Biotechnology can lead to a decrease in the use of pesticides through several mechanisms. One way is by genetically modifying crops to be resistant to pests. This reduces the need for pesticide application as the crops are naturally protected.
Another way is by introducing natural predators of pests. These predators can help control pest populations and reduce the reliance on chemical pesticides. Additionally, biotechnology can enhance crop immunity, making them more resistant to diseases and pests, further reducing the need for pesticide use.
