The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, human organism.
The atom is the basic building block for all matter in the universe.
All matter is made up of substances called Elements it's a substance that consists of only one type of atom for Example: oxygen
All elements are made up of atoms.
Atom is the smallest unit of element are made up of proton, neutron, and electron.
