B... These microbes are the foundation for life in hydrothermal vent ecosystems. Instead of using light energy to turn carbon dioxide into sugar like plants do, they harvest chemical energy from the minerals and chemical compounds that spew from the vents—a process known as chemosynthesis . (I got this off the web hope it helps)
The kind of monomers that make up the lipids are the fatty acid and the glycerol.
Lipids or the fats are the organic compounds containing two kinds of monomers called the fatty acid and the glycerol. Fatty acids are the carboxylic acids made up of a hydrocarbon chain with a terminal hydroxyl group. Glycerol is an alcohol containing three carbon, five hydrogen and multiple hydroxyl groups (usually three) and it forms the back bone of all the lipids. The most abundant lipid called the triglycerides are the esters of fatty acids and glycerol.
