What is the role of sulfur in the sulfur cycle decomposition
     What is the role of sulfur  in the sulfur cycle?  decomposition  reduction  oxidation  Reduction of CO_2 to generate carbohydrates can occur when coupled to the oxidation reduced s compounds (for example, has). This latter process is carried out by what type of  ?   
  
  Solution
10. Oxidation- is the role of sulfur chemoautotrophs in the sulfur cycle
chemoautotrophs anrganism that derives its energy from chemical processes rather than photosynthesis
11. Reduction of co2 to generate carbohydrates can occur when coupled to the oxidation of reduced sulphur compounds. the latter type of process is carried out by Sulphate reducers
