Question

sewage, manure, farm runoff, and fertilizers are associated with what type of water pollution?
atmospheric
radioactive
inorganic nutrient
thermal

Explanation:

Sewage, manure, farm runoff, and fertilizers often introduce nutrients like nitrogen and phosphorus (inorganic nutrients) into water bodies, causing eutrophication. Atmospheric pollution relates to air, radioactive pollution involves radioactive substances, and thermal pollution is about temperature changes. So the correct option is the one related to inorganic nutrient pollution.

Answer:

inorganic nutrient (the option labeled "inorganic nutrient")
