Cellular respiration is an important metabolic process that moves sulfur from living organisms into the atmosphere.
Explanation:
Cellular respiration is mainly based in the carbon cycle, because most of the compounds involved have carbon in it structure.
sulfur can release to the atmosphere by burning fossil fuels or by volcanic eruptions in the form of SO2, this is a normal gas, despite is a toxic gas, but the quantities that are formed are too little.
