The excess algae and plant matter eventually decompose, producing large amounts of carbon dioxide. This lowers the pH of seawater, a process known as ocean acidification. Read This! In healthy aquatic ecosystems there is a balance of two quantities—the concentration of dissolved oxygen (D.O.) and the biological oxygen demand (B.O.D.).You might think that biological oxygen demand is the oxygen needed by the fish and other aquatic life in the lake, but it is actually the organisms you cannot see that are most important. . Biological oxygen demand is the amount ...

Eutrophication is a process that leads to enrichment of ponds, lakes and any water body with minerals such as nitrogen and phosphorus. Aquatic ecosystems are diverse and consists of phytoplanktons, zooplanktons, fish and other animals. Too much enrichment of the ecosystem adversely effects the flora and fauna of the aquatic bodies.
