What term describes water with no dissolved oxygen?

Explanation:
Dissolved oxygen levels in water define whether it is oxic, hypoxic, or anoxic. Anoxic water has no detectable dissolved oxygen, so aquatic organisms cannot rely on it for respiration. Hypoxic water has very low but nonzero oxygen, which stresses life but isn’t completely devoid of it. A dead zone refers to a larger area with persistent low or no oxygen often caused by nutrient-driven eutrophication, not the single-water state itself. Turbidity measures how clear the water is due to suspended particles and does not indicate oxygen content.
