Which statement describes both a positive impact and a negative impact associated with the effects of nitrogen-enhanced fertilizers? They increase polluted runoff and damage drinking water.
They increase plant growth and damage drinking water.
They increase denitrifying bacteria and increase plant growth.
They increase both limiting resources and denitrifying bacteria.

Explanation:

Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body

Hence, option B is correct
