Sulfur Cycle Diagram Explanation. Plants absorb sulphur when it is dissolved in water. The sulfur cycle of the surface ocean begins with the assimilatory uptake of sulfate by phytoplankton both eukary otic algae and prokaryotic cyanobacte ria figure 1.
Sulfur occurs in all living matter as a component of certain amino acids. From the decomposition of organic molecules from volcanic activity and geothermal vents and from the burning of fossil fuels by humans. Some sulfate is incor porated in oxidized form into sulfated polysaccharides eg mucus but most figure 1.

Bacteria can mediate these oxidations. Hoso2 o2 ho 2 so 3 in the presence of water sulfur trioxide soin the presence of water sulfur trioxide so 3 is converted is converted rapidly to sulfuric acid. It acts as either electron donor or acceptor in many bacterially mediated reactions. Sulfur cycle definition steps diagram importance.
