Nutrient pollution causing oxygen loss in water is called what?

Explanation:
Excess nutrients in water fuel algal blooms and dense plant growth. When these organisms die, microbes decompose them and consume dissolved oxygen, leading to low-oxygen conditions that stress or kill aquatic life. This sequence of nutrient enrichment followed by oxygen depletion is eutrophication. The other terms describe where pollution comes from or general transfer rates, but they don’t name the ecological change that causes the oxygen loss.
