The simplest level of organization as far as taxonomy goes would be the most inclusive one; a domain. If you are asking in terms of things such as organisms, it would be the smallest, the cell.

cells
The lowest level of organization that includes atoms and molecules is the chemical level. This is the level that maintains life.
Cells are the most basic unit of organization in the body, and the cellular level is the most basic level of organization. Cells joint to for tissues, which form organs, which form organ systems, which form organisms.cell, tissue, organ, organ system, and the organism
Levels of organization are the way Biology is layered in a hierarchy. For example, organs make up one level, as the fourth level of organization.
