a) Carbohydrates are classified as polysaccharides and monosaccharides. Polysaccharides are polymers of monosaccharides(monomer). Example - Starch is a polymer of glucose(monomer). b) Protein is a polymer of amino acid (monomer). Example - polymers is polypeptide, monomers are amino acids. c) In case of nucleic acid for example- Nucleotides are monomers (adenine, guanine, thymine, cytosine, uracil) and polymers are DNA & RNA (Nucleic acid).
