Question

Write three causes and three effects of cultural eutrophication.

Accepted Answer

Eutrophication may be defined as the inorganic nutrient enrichment of natural waters, leading to increased production of algae and macrophytes.

Causes of Eutrophication:

Eutrophication is predominantly caused by human actions due to their dependence on using nitrate and phosphate fertilizers.

The concentrated animal feeding operations normally discharge high scores of the nutrients that find a way into rivers, streams, lakes and oceans where they accumulate in high concentrations.

In some parts of the world, especially the developing nations, sewage water is directly discharged into water bodies such as rivers, lakes and oceans.

Effects of Eutrophication:

Increased biomass of epiphytic and benthic algae can be observed in eutrophic waters.

The water loses its transparency and develops a bad smell and colour. The treatment of this water becomes difficult.

Depletion of dissolved oxygen in the water body.
