Answer

Answer:

B. They increase plant growth and damage drinking water.

Explanation:

Step1: Analyze positive impact

Nitrogen - enhanced fertilizers provide nitrogen which is essential for plant growth, promoting processes like photosynthesis and protein synthesis, thus increasing plant growth.

Step2: Analyze negative impact

Excess nitrogen from these fertilizers can leach into water sources through runoff. This can cause eutrophication in water bodies and contaminate drinking - water sources, making them harmful for human consumption.

Step3: Evaluate options

  • Option A only mentions negative impacts (increased polluted runoff and damage to drinking water).
  • Option B has both a positive (increase plant growth) and a negative (damage drinking water) impact.
  • Option C has two positive - sounding impacts (increase denitrifying bacteria and increase plant growth).
  • Option D has two impacts that are not clearly positive and negative in the context of the question (increase limiting resources and denitrifying bacteria). So, the answer is B.
