     What is the role of sulfur chemoautotrophs in the sulfur cycle?  Decomposition  reduction  oxidation  assimilation  Reduction of CO2 to generate carbohydrates can occur when coupled to the oxidation of reduced sulfur compounds (for examples, H2S). This latter process is carried out by what type of  sulfate oxidizers  sulfate reducers 
  
  Solution
10
Oxidation
Sulfur chemotrophs oxidize sufur to derive energy for the synthesis of ATP
