A newly discovered organism is found to use hydrogen sulfide H₂S) for aerobic respiration and carbon dioxide CO₂) from the air as a source of carbon, much like a plant. This organism must be a

Question

Quizplus · Accepted Answer

The organism is using hydrogen sulfide for energy (chemolitho-) and carbon dioxide from the air as a source of carbon (-autotroph). It is not using light as an energy source, so it is not a photoautotroph. It is also not using organic compounds as a source of energy, so it is not a chemoorganoautotroph or a chemolithotrophic heterotroph.
