(Microbiologyprocedure, 2008) 8. the SULPHUR isabsorbedfor use a PRODUCT excreted inanother form What Happens? 9. years ofRESEARCHhas been performedonnutrient cycles& how this occurs

the next picture :shows the cycle ofsulphur

observe what occurs in the soil & ocean

microbes areessentialwithin this process
