Solution Steps

Step 1: Analyze the question

The question asks about the negative impact of over-fertilizing on water.

Step 2: Consider the options
  • Increased clarity: Fertilizers typically add nutrients and promote algae growth, reducing water clarity.
  • A decrease in sediments: Fertilizers don't directly reduce sediments.
  • Eutrophication: This is the excessive growth of algae due to nutrient runoff (like fertilizers), leading to oxygen depletion and harming aquatic life.
  • Increased dissolved oxygen: While initial algae growth might slightly increase oxygen, the subsequent decomposition consumes it, leading to a net decrease.
Step 3: Choose the most accurate answer

Eutrophication is the primary negative consequence of fertilizer runoff in water bodies.

Final Answer

eutrophication
