Detailed explanation-2: -Some of the most common carbon compounds are: carbon dioxide (CO2), carbon monoxide (CO), carbon disulfide (CS2), chloroform (CHCl3), carbon tetrachloride (CCl4), methane (CH4), ethylene (C2H4), acetylene (C2H2), benzene (C6H6), ethyl alcohol (C2H5OH) and acetic acid (CH3COOH).
Detailed explanation-3: -The four classes of organic carbon compounds used by microbes are carbohydrates, fats, proteins, nucleic acids. The five examples are glucose, maltose, sucrose, glycogen, and cellulose.
Detailed explanation-4: -Bioinorganic substances do not contain carbon, for example water and inorganic salts. On the other hand bioorganic substances contain carbon, for example lipids and carbohydrates.
