Which answer gives both a positive impact and a negative impact that are associated with the effects of nitrogen- and phosphorus-enhanced fertilizers? a. increased algal blooms and damage to drinking water. b. increased plant growth and damage to drinking water. c. increase in denitrifying bacteria and increase in plant growth. d. increase in a limiting resource and increase in denitrifying bacteria

Answer;

B. increased plant growth and damage to drinking water.

Explanation;Nitrogen and phosphorous are major determinants of plant growth and productivity, therefore nitrogen and phosphorus enhanced fertilizers are important for increased growth of plants.However, nitrogen- and phosphorus-enhanced fertilizers may have negative impacts on the environment which includes eutrophication, where nitrates and phosphates are flooded into lakes and oceans and result to the growth of algae in water bodies, which damage drinking water and also affect the aquatic life.
