In what way does biotechnology benefit agricultural productivity?

• A. By reducing the use of water in farming
• B. By enhancing crop yields and improving pest resistance
• C. By eliminating the need for crop rotation
• D. By promoting the use of more chemical fertilizers

Answer: (B)

Biotechnology significantly benefits agricultural productivity primarily through the enhancement of crop yields and the improvement of pest resistance. This technology involves the manipulation of plant genetics to develop new traits that can lead to higher productivity. For instance, biotechnological advancements can create crops that are genetically engineered to resist specific pests, reducing the need for chemical pesticides and thus lowering production costs for farmers. Additionally, enhanced crop traits such as drought resistance, stress tolerance, and improved nutritional content contribute to more robust harvests. These innovations ultimately lead to increased food supply and sustainability in agriculture, meeting the demands of a growing global population.

The other options do not effectively capture the primary advantages offered by biotechnology. For example, while biotechnology can contribute to water-efficient practices, its main benefits lie in yield and pest resistance rather than solely reducing water use. Additionally, while crop rotation is a valuable agricultural practice, biotechnology does not eliminate the need for it; rather, it can work in conjunction with such practices to optimize soil health and farming systems. Lastly, promoting the use of more chemical fertilizers is counterproductive to the goals of sustainability that biotech aims to support, as it seeks to reduce reliance on excess chemicals in farming.
