It decreases dissolved oxygen of water. It is a phenomenon of nutrient enrichment of a water body. Select the correct answer from the codes given below. Eutrophication is defined as the enrichment of a water body with nutrients, primarily phosphorus and nitrogen (Statement 2 is correct). This excessive nutrient load leads to rapid growth of algae and aquatic plants, often resulting in algal blooms. When these organisms die, their decomposition by aerobic bacteria consumes large amounts of dissolved oxygen in the water, leading to hypoxia or anoxia, which can kill fish and other aquatic life (Statement 1 is correct).
