One way to group organism is by the way they obtain carbon b/c carbon is the backbone to all organisms. Autotrophs synthesize organic carbon by using inorganic carbon (carbon dioxide) Heterotrophs obtain carbon from organic molecules (other organisms) Organisms can be divided according to the source of energy they use for biological activities. Chemotrophs obtain energy by oxidizing inorganic or organic substances.
