Natural eutrophication and cultural eutrophication
Answers
Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.

Natural eutrophicatio is the process by which lakes gradually age and become more productive. ... Cultural or artificial eutrophication occurs when human activity introduces increased amounts of these nutrients, which speed up plant growth and eventually choke the lake of all of its animal life.
Natural Eutrophication - Natural Eutrophication is a natural process that occurs in an aging lake or pond as that body of water gradually builds up its concentration of plant nutrients.
Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.
The difference between natural eutrophication and cultural eutrophication is that cultural eutrophication is caused by human beings. Natural eutrophication is a natural and long process which may take several decades or even millennia to complete. It is primarily caused by deposition of sediments. Cultural eutrophication can be rapid and it is caused by activities such as landscaping and farming which result in increased runoff as well as artificially high levels of nutrients in the soil.
