Which of the following pollutants is most responsible for causing eutrophication in water bodies?
Which of the following pollutants is most responsible for causing eutrophication in water bodies?
hard Q9 of 15
Step-by-Step Solution
Step 1: Understand eutrophication
Eutrophication is the excessive growth of algae due to nutrient enrichment in water.Step 2: Identify nutrients causing eutrophication
Excess nitrates and phosphates from fertilizers cause algal blooms, depleting oxygen and harming aquatic life. Carbon monoxide and sulfur dioxide are air pollutants, not nutrients. Lead compounds are toxic but do not cause eutrophication.Step 3: Why other options are incorrect
Carbon monoxide is a toxic gas affecting respiration, not water nutrient levels. Sulfur dioxide causes acid rain, not eutrophication. Lead compounds cause heavy metal toxicity, unrelated to nutrient enrichment.Final Answer:
Excess nitrates and phosphates → Option AQuick Check:
Eutrophication cause = Excess nitrates and phosphates ✅
Quick Trick: Remember fertilizers cause eutrophication via nitrates and phosphates.
Common Mistakes:
- Confusing air pollutants with water nutrient pollutants.
