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

Correct B) Increased plant growth and damage to drinking water

The excess use of phosphorous and nitrogen in the fertilizers have a bad effect on the environment. Due to over use of fertilizers such as phosphorous and nitrogen it result in leaching of the fertilizers to the soil which cause serious environmental damage to the soil and the water bodies.

Leaching is the process which leads to loss of water soluble plant nutrients from the soil because of irrigation or due to rain.

It moves through the soil in to the water  bodies and cause algal bloom which pollute the water environment and deteriorate the water quality.
