What term describes a rapid increase in algae due to nutrient overload?

• A. Dissolved Oxygen Levels
• B. Algal Blooms
• C. Common Groundwater Pollutants
• D. Fracking

Answer: (B)

When nutrients such as nitrogen and phosphorus flood a water body, algae can multiply rapidly, producing an algal bloom. Fertilizer runoff, sewage, and other sources raise these nutrient levels, fueling fast growth of algae on the surface or throughout the water. This sudden bloom can color the water, reduce light for submerged plants, and, as the algae die and decompose, consume dissolved oxygen, potentially creating low-oxygen conditions that stress or kill other aquatic life. That combination of rapid growth driven by nutrient input is exactly what the term algal blooms describes. Dissolved oxygen levels describe how much oxygen is present in the water, not the rapid increase in algae. Common groundwater pollutants refer to contaminants found in groundwater, not the algal response to nutrients. Fracking is a drilling method and not related to algae growth dynamics.
