Energy flows from producers to primary consumers, to secondary consumers, to tertiary consumers... Energy is lost between trophic levels in the form of heat through cell respiration, faeces, tissue loss and death. Some of this lost energy is used by detritivores and saprotrophs.
Methanol, acetone, and isopropanol belong to the first group. These substances were detected and proposed as alcoholism indicators in connection with congener alcohol analyses of blood samples from DWIs. Methanol, in particular, has been adopted as a powerful indicator of alcohol misuse.
Best Answer: They are not the same--actually, they are very different. But one has to know a bit of organic chemistry to appreciate the difference. Acetone is a KETONE, and iso-propanol (rubbing alcohol) is an ALCOHOL. Or classified another way, ketones are polar aprotic [note the 'a' in aprotic] solvents; alcohols are polar protic solvents. It is the polar aprotic nature of actone that allows it to dissolve fingernail polish. Acetone is also used as paint thinner, among other things.
