how we differentiate between elements it is micromolecule and macromolecule?
Your query is not clear. However I am providing you the answer for what are macromolecules and micromolecules and difference between them.
A biomolecule is any molecule that is produced by a living organism , including large macromolecules such asproteins , polysaccharides , lipids , and nucleic acids , as well as small molecules such as primary metabolites ,secondary metabolites , and natural products . The small biomolecules also called micromolecules are the biomolecules which have molecular weight less than 1000 Da (Dalton). Biomacromolecules are the biomolecules which have molecular weights higher than 1000daltons (Da) approximately and found in the acid soluble pool in the chemical analysis of the living tissue. For e.g. proteins, nucleic acids and polysaccharides .
