Some additional remarks:
1. The first level as macro-level has specific characteristics of being a gateway to other macro-levels. To give an example: archetypes occur as symbols in thought and speech. Language forms a gateway from the individual to the collective, across space and time. Long after someone is dead, his or her words may continue to have an influence on people through written word, audio or videorecordings, etc.
2. The process of communication may yield fresh insights as to the usebility of the model. Four aspects of communication must be researched.
3. Human brain has, relative to the body, a global function. The neocortex is heavily involved in language and symbolic processing. Also, the brain influences organs locally by secreting hormones and neurotransmitters. These can be seen as messengers.
4. The second level shows evaluative function. The regulation of emotion through norm and meta-emotion is subject of research. Complicated networks of meaning arise through experience, education, etc.
There seems to be some inherent fuzziness associated with this level (and sublevel two of levels in general). From elementary particles to ever shifting shades of meaning, all very fuzzy.
5. On the cell level one can see the famous "key-lock" "mechanism" operating in binding of substances to receptors. One can see this as an evaluative mechanism: a protein fits in the lock or it doesn't. If it does a whole sequence of steps follows (a program).
6. All the above bears testimony to the meta-model I have sketched thus far. It must all be carefully reseached, of course. Many more examples must be charted from literature and experience and some general observations and philosophical considerations must be made before we can conclude that the meta-model holds true in general. This model might subdivide in more detailed models subsequently, depending on the field of study.
