Single cell paramesium would be the least complex then up through cells of the blood and brain onto multi cellular slugs. Once you get to levels of orgainisation that have speciallised cells for motion, digestion, vision etc then where the creature can live becomes a factor. What is called the 'tree of life' gives more detail but it is a long and increasingly complex ange of creatures involved

The levels of organization from least to most complex are:AtomsMoleculesCellTissueOrganOrgan system
What has the least complex organization an organism an organ a population or a cell?
A cell has the least complex organization, as it is the basic structural and functional unit of all living organisms. Cells are the building blocks of life and have a simple structure compared to organs, organisms, and populations.
