Hypoxia, or low levels of oxygen.
Explanation: Eutrophication adds nutrients (from fertilizers, etc.), causing algal and aquatic plant overgrowth. When that biomass dies, decomposition by microbes increases and consumes dissolved oxygen, producing hypoxic or anoxic conditions. The other options are incorrect: eutrophication causes overgrowth (not undergrowth), increases (not decreases) decomposition, and involves active nutrient inputs (not inactive fertilizers).
