Definition of Systemic Functional Level (SFL in english)

The Systemic Functional Level (SFL) would be a measure or degree of a system's functioning in terms of increasing complexity, given by the combination of matter, energy, and information. The amount of information generated, stored, transmitted, and processed by it has a greater "weight" than the other two "variables." For example, we have less mass than a lion, we expend less energy, but the amount of information we process, due to our brain, makes the SFL higher. Since we are dealing with complex systems, it's impossible to put all this into formulas, but it would be something like mass x energy x information; and it can be different.

If it grows, the Functional Information also grows, being dependent on it.

Example:

T-Rex vs. Human. The dinosaur possessed tons of mass and energy, but a limited SFL due to its information processing capacity. The human brain, weighing only 1.3 kg and consuming the energy of a 20W LED light bulb, achieves a higher NFS (LIFI) because the efficiency of functional information "leverages" the system to a new phase transition, a higher level.
