This diagram explains the formation of dead zones:
Figure 14: This is a diagram explaining how
Eutrophication works. Using the information from the graph we can see that
eutrophication is caused by nutrient enrichment due to the input of nitrogen and
phosphorus. The nutrient enrichment causes an increase in phytoplankton, which
then grows on sedgegrass, which in return, causes algal bloom. The result of
algal bloom causes the loss of food, habitat and oxygen production. The blockage
of sunlight due to the sediments from land also contribute to the process of
eutrophication. From this information, we can comprehend how the input of
nitrogen and phosphorus causes algal bloom and therefore can conclude that
nutrient enrichment causes the loss of food, habitat and oxygen production.

There are many causes to dead zones but it is important that we identify the major causes in order to solve the issue:
