The sequence of biological organization from the simplest to the most complex is: cell, tissue, organ, organ system, organism. Each level builds upon the previous one, with cells being the basic unit of life and organisms being the most complex level with multiple organ systems working together.

The correct order from simplest to most complex would be: cells, tissues, organs, organ systems, human body.
The correct structural order from simplest to most complex is atom, molecule, organelle, cell, tissue, organ, organ system, and organism.
The earliest cells came before the most complex organisms existing today. :]
The simplest form of matter is an element, which consists of only one type of atom. Compounds are more complex forms of matter, consisting of two or more different elements chemically bonded together. The most complex forms of matter are materials like proteins, DNA, or polymers, which are made up of complex arrangements of atoms and molecules.
