Can an organism exist simultaneously at several levels of an organization?

Living organisms can simultaneously exist at several levels of an organization. Let’s consider everything on the example of a person. We are made up of organ systems, which are made up of various tissues, tissues are made of cells, and cells are made of molecules. Therefore, we exist simultaneously at the molecular, cellular, tissue, organ and organismal levels.

Discreteness of an organism lies in the fact that all its parts are interconnected. For example, some hormones and enzymes regulate the actions of other organ and tissue systems in the body.
