Explanation:
Eutrophication occurs due to the increased concentration of natural nutrients. Conversely, artificial eutrophication happens due to human activities.
<h3>Eutrophication and artificial eutrophication</h3>
Eutrophication is a biological phenomenon that occurs due to the increased concentration of natural nutrients such as algae in a water body.
Artificial eutrophication is a specific type of eutrophication process caused by human activities.
Artificial eutrophication can be caused, for example, for an excessive overload of fertilizers in a lake.
