The macromolecule that is not organized in repeating units of monomers is water (H₂O).

Here's why:

* Monomers: Monomers are small, simple molecules that serve as building blocks for larger polymers. Examples include sugars (monosaccharides), amino acids, nucleotides, and fatty acids.

* Polymers: Polymers are large molecules made up of repeating units of monomers. Examples include carbohydrates, proteins, nucleic acids, and lipids.

Water is a simple molecule and does not consist of repeating units of smaller molecules. It is formed by the covalent bonding of two hydrogen atoms and one oxygen atom.
