-.Which of the following human activities adds the amount of nitrogen and phosphorus to the soil and can lead to cultural eutrophication? A. Fossil Fuels. B. Fertilizers. C. Evaporation. D. Precipitation

B. Fertilizers

Explanation:

Adding fertilizers causes eutrophication which leads to nutrient glut.

The use of fertilizers in farmland can lead to addition of significant amount of nitrogen and phosphorus into nearby water bodies. Fertilizers are made up of nitrogen and phosphorous compounds. When the fertilizer is washed into streams and lakes, they cause the rapid increase in nitrogen and phosphorous in the water.
