Answer:
algal growth due to eutrophication
Explaination:
Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.
