What is the correct sequence of eutrophication?

Answer 1

Eutrophication typically begins with the introduction of excess nutrients, particularly nitrogen and phosphorus, into a water body, often from agricultural runoff or wastewater. This nutrient influx stimulates algal blooms, which can block sunlight and deplete oxygen levels in the water as they decay. The resulting hypoxic conditions can lead to the death of aquatic life, causing a decline in biodiversity and disrupting the ecosystem. Ultimately, this process can result in the formation of dead zones where few organisms can survive.
