Many lakes are naturally eutrophic and in some cases there is a progressive eutrophication as the lake matures. The difference between natural eutrophication and cultural eutrophication is that cultural eutrophication is caused by human beings. Answer:The difference between natural eutrophication and cultural eutrophication is that cultural eutrophication is caused by human beings. Cultural eutrophication happens when the amount of nutrients in the water and/or the water temperature are changed due to human activity, and the eutrophication process begins to run at high speed.

Cultural or anthropogenic eutrophication is the process that speeds up natural eutrophication because of human activity. 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. Biomagnification is also called Bioamplification. This is termed cultural eutrophication and in many parts of the world has resulted in a number of deleterious effects to ecosystems.
