Ammonium nitrate addition to wetland soil cores is associated with increased CO₂ efflux, presumably caused by the increased respiration by: A) phototrophs B) autotrophs C) heterotrophs D) lithotrophs E) methanogens

Question

Quizplus · Accepted Answer

Ammonium nitrate addition to wetland soil cores can increase the availability of nitrogen to soil microorganisms, leading to increased microbial activity and respiration. This increased respiration is likely due to the activities of heterotrophic microorganisms, which rely on organic carbon for energy and use nitrogen compounds as a source of nutrients. The other options (A, B, D, and E) are not directly related to the effects of ammonium nitrate addition on microbial respiration in wetland soils.
