What characterizes a 'Eutrophic' body of water?

A 'Eutrophic' body of water is characterized by being nutrient-enriched, particularly due to contributions from runoff or septic systems. This enrichment often leads to increased levels of nutrients like nitrogen and phosphorus, which promote excessive algal blooms. As algae decompose, they consume oxygen in the water, leading to lower oxygen levels that can harm aquatic life. Eutrophic waters typically exhibit a rich biological productivity but can also experience significant ecological challenges due to these nutrient levels. This differentiation is crucial in understanding aquatic ecosystems, as it highlights the impact of human activities on water quality and the health of aquatic environments.
