Systemic Functional Level Definition

It is a measure of a system's structure and functioning, based on the amount of matter, energy, and functional information it contains. 

I define it as the functioning of a system itself, which encompasses a certain measure of the variables of matter, energy, and functional information. Functional information is that which is useful and meaningful to the system's performance. 

It serves as a parameter for evaluating the structure and functioning of the system. It is a satisfactory way to explain how different systems work. 

The central idea is that a system can increase its functional level when there is an increase in the quantity and flow of matter, energy, and functional information, leading it to a "phase transition" from a lower to a higher plane of functioning. 

The systemic functional level reveals the proportion and interaction between matter, energy, and functional information within a system, indicating its capacity to operate and evolve. A notable example is the human brain, which, despite its small mass and low neuroelectric power, demonstrates an extremely high systemic functional level due to its complex information processing.
