Consider the chemical reactions of the sulfur cycle shown in Figure 26.10. Reduction of CO₂ to generate carbohydrates can occur when coupled to the oxidation of reduced sulfur compounds (e.g., H₂S). This latter process is carried out by what type of microorganism(s)?

Question

Quizplus · Accepted Answer

Chemoautotrophs are the type of microorganisms that can carry out the oxidation of reduced sulfur compounds and generate carbohydrates. Heterotrophs cannot carry out this process. Therefore, the best choice is A (chemoautotrophs).
