Which problem is most likely linked to high levels of total suspended solids (TSS)?

High levels of total suspended solids (TSS) in water bodies are primarily composed of particles such as silt, clay, and organic matter that can cloud water. This sediment can significantly reduce light penetration in the water column. When light is unable to reach aquatic plants and phytoplankton, it adversely affects photosynthesis, which is essential for these organisms’ growth and survival. Reduced photosynthesis leads to lower oxygen levels in the water, negatively impacting the entire aquatic ecosystem.

The other options do not accurately reflect the consequences of high TSS levels. For instance, improved underwater visibility and reduced algae growth would generally be associated with lower TSS levels, not higher. Enhanced habitat for larger fish also depends on clear water and healthy plant life, which high TSS levels can damage. Thus, the correct answer highlights the detrimental effects of TSS on light penetration and photosynthesis in aquatic environments.
