The molecule is not the lowest organization of life because atoms joined together to form molecules since they are smaller they come first.
Explanation:
Atom > Molecule > Cell > Tissue > Organ > Organism > Population > communities>Ecosystem > Biosphere. This is the hierarchy of organization of life, where atom is proceeded by molecules. Since atoms are the smallest level that makes elements.
Like O2, H2, cellulose are molecules of organisation of life, made up of atoms.
