Vedclass · Answer

(A) Eutrophication is the process of nutrient enrichment (especially nitrogen and phosphorus) in water bodies,which promotes excessive growth of algae (algal bloom). As these algae die,their decomposition by microorganisms consumes a large amount of dissolved oxygen in the water. This leads to a significant decrease in the biological oxygen demand $(BOD)$ and dissolved oxygen levels,causing aquatic organisms like fish to die due to suffocation (lack of oxygen).

In water bodies,fish die due to eutrophication because of the lack of which of the following?
