Which of the following best describes the effect of increased sediment in surface water?

Increased sediment in surface water primarily leads to decreased clarity, which can significantly hinder light penetration. This reduced clarity can affect photosynthesis in aquatic plants and disrupt the overall health of ecosystems. Furthermore, higher sediment levels can smother aquatic habitats, restrict the movement and feeding of fish and other organisms, and contribute to the potential release of toxins or pollutants adhered to the sediment particles, causing harm to aquatic organisms. Therefore, option B accurately reflects the negative impacts of increased sediment, emphasizing both clarity reduction and the potential harm to aquatic life.
