Which long-term outcome results when sediment blocks tributary inflow to river-fed lakes?

💡 Explanation

Nutrient starvation results because blocked inflow reduces nutrient supply – a nutrient cycle interruption mechanism – leading to a lower trophic state; therefore less algae grows, rather than higher concentration/stratification (driven by different mechanisms) or external flood risk.
