excess nitrogen from fertilizers running into waterways can cause—
a. soil erosion
b. deforestation
c. algal blooms that reduce oxygen in water
d. more nitrogen gas in the atmosphere

Explanation:

Excess nitrogen from fertilizers in waterways acts as a nutrient boost for algae. Algal blooms occur, and when the algae die and decompose, oxygen is consumed, leading to oxygen - depleted water. Soil erosion is mainly related to factors like lack of vegetation and water/ wind action on soil. Deforestation is about the removal of forests. The nitrogen from fertilizers running into waterways doesn't directly lead to more nitrogen gas in the atmosphere in this context.

Answer:

C. Algal blooms that reduce oxygen in water
