Question

There is a hypoxic dead zone in the Gulf of Mexico due to nitrogen-rich runoff from the Mississippi River. When the Mississippi flows into the Gulf of Mexico, it introduces high levels of organic pollutants and nitrates from fertilizers. The presence of these excess nitrogen-rich substances in the Gulf of Mexico leads to a sequence of events that results in the hypoxic dead zone. Put these events, which are listed below, in sequential order.
