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

Option b

Explanation: We need to find an answer which is associated with both a positive and a negative impact associated with effects of nitrogen and phosphorous enhanced fertilizers.

Use of fertilizers increase algal blooms and create problems such as poisoning and damage to fisheries, thus a negative impact.

Excess use of fertilizers create damage to drinking water, thus a negative impact.

Nitrogen and phosphorous are essential for plant growth and a positive impact.

Use of fertilizers do not affect the denitrifying bacteria.

Thus increase in plant growth is a positive impact and damage to drinking water is a negative impact.
