How are the various levels of organization of living matter interconnected?

Each level of organization is determined by a group of backbone factors, that is, factors that are leading in the formation of the system. But, there is always a group of related backbone factors, the unifying factor within each level of organization is the metabolism, which is characteristic of this level. But despite the specifics of each of the levels of organization, they are all connected and obey the general laws of the existence of living matter. Each next level of organization is a consequence of the previous one. The factor that unites all levels of organization into a single whole is biotic metabolism.
