The Levels of Organization is a term used in basic Biology, anatomy, and physiology. It is used with five basic concepts, the smallest the cell. Many specialized cells make up a tissue, many tissues an organ, many organs an organ system, and finally, many organ systems an organism. In bizarre cases microorganisms (unicellular) and superorganisms, only one cell or many organisms may occur within a single species or organism.
