What function does sedimentation serve in controlling aquatic pests?

• A. It promotes nutrient growth for pests
• B. It reduces aquatic plant and algae growth
• C. It increases water temperature
• D. It has no effect on pest populations

Answer: (B)

Sedimentation plays a significant role in controlling aquatic pests by reducing the available light and the nutrient supply required for the growth of algae and aquatic plants. When sediments settle at the bottom of a body of water, they can cover plants and inhibit photosynthesis, which in turn diminishes the growth of both harmful pests and their food sources. Additionally, sedimentation can lead to a more stable ecosystem, where the balanced habitat conditions discourage the proliferation of specific pest populations. By limiting the growth of unwanted aquatic plants and algae, sedimentation acts as a natural control method, maintaining healthier water quality and reducing the potential for pest outbreaks.
