Which of the following can stabilize sediments in water bodies?

Aquatic vegetation plays a crucial role in stabilizing sediments in water bodies. The roots of these plants anchor the soil and sediment on the bottom, preventing erosion and keeping sediment in place. This stabilization is essential in maintaining water quality, as excessive sediment can lead to increased turbidity, which affects light penetration and can harm aquatic ecosystems.

When aquatic plants are present, they can also help reduce water flow velocity, allowing sediment to settle rather than be resuspended into the water column. Additionally, these plants serve as habitats for various aquatic organisms and contribute to nutrient cycling within the ecosystem.

In contrast, the other options do not contribute positively to sediment stabilization. Fecal coliform is an indicator of bacterial contamination and does not play a role in sediment stabilization. Water temperature can affect the physical and chemical properties of the water but does not directly stabilize sediments. Pollution can exacerbate sediment problems by adding harmful substances that may lead to further destabilization of sediments rather than their stabilization.
