What is one benefit of using genetically modified crop species like Bt corn?

• A. Increases soil fertility
• B. Increases the crop yield
• C. Reduces the need for pesticides
• D. Enhances flavor of the crops

Answer: (B)

Using genetically modified crop species like Bt corn offers several notable advantages, and one significant benefit is the reduction in the need for pesticides. Bt corn is engineered to express a protein from the bacterium Bacillus thuringiensis, which is toxic to certain pests, particularly moth larvae. This inherent pest resistance leads to less reliance on chemical insecticides to protect the crop from infestations, which not only reduces production costs for farmers but also minimizes the environmental impact typically associated with pesticide usage.

The modification allows for greater efficiency in pest management, promoting healthier crop growth and potentially leading to increased overall yields as crops can thrive without the stress of pest damage. When pests are controlled more effectively through the plant’s own defenses, the likelihood of significant crop losses decreases, thereby contributing to stable or higher yield outcomes. Additionally, using Bt corn can mean fewer pesticide applications are necessary, which can improve safety for agricultural workers and reduce pesticide runoff into nearby ecosystems.

The other options presented focus on aspects such as soil fertility and flavor enhancements, which are not direct benefits attributed to genetically modified organisms like Bt corn. While increased crop yield can be a consequence of better pest control, it isn't the primary or guaranteed result solely from genetic modification, making the reduction of pesticide dependency a more accurate
