No, but most macromolecules are organic molecules (with a backbone made of carbon atoms). But it is possible to synthetically create macromolecules with a backbone made of silicon atoms (i.e. the silicones), boron atoms (i.e. the boranes), and a few others. The atoms attached to the backbone or forming side branches extending away from the backbone can be any element on the Periodic Table.
they are all formed from the same elements.
All macromolecules contain a monomer.
Macromolecules are formed from many simple molecules (monomers) and have a big molecular mass.

There are three elements. they are C,H,and O.

They are all formed from the same elements.
They are all organic compounds, that is they contain carbon. They all contain hydrogen and oxygen too. Proteins and nucleic acids additionally have nitrogen, and nucleic acids have phosphorus. In addition, proteins, nucleic acids and polysaccharides like starch (but not simple sugars) are macromolecules.
