What are the reasons for Eutrophication in water eco system?
Answers
Eutrophication is characterized by dense algal and plant growth owing to increased concentration of chemical nutrients needed for photosynthesis. It mainly arises from the oversupply of phosphate and nitrate nutrients. As such, increased levels of chemical nutrients from animal waste, fertilizers and sewage often give rise to eutrophication when washed into nearby surface waters by rain or irrigation.
Eutrophication also occur natural over thousands of years as the lakes grow old and filled with sediments. Still, human activities have sped up the degree and rate of eutrophication through both point-source and non-point source discharges of the chemical nutrients (phosphates and nitrates) into aquatic systems. Some of the consequences of eutrophication include destruction of aquatic systems and reduction in water quality.
