What I am not clear about here is not the definitions but how the apply in
terms of systems where the inter-relationships are so complex. Let's think
of an organizaiton of ten people who in dyads have various combinations of
the above, in chains, etc. Of what use are the distinctions? I see how it
applies with two organisms but not to eco-systems.
