[Levels] Biology. [Description] 
Studies life-processes in terms of their structure and function are based on the carbon-based macromolecules of biochemistry.

People are composed of these complex molecules (an interesting "pile" of molecules in a certain form).
Leo Tolstoy, "Only Faith Can Give Truth"
