The analysis described above allowed that an important
relationship between the net primary production and the
soil respiration of terrestrial ecosystems could be found.
Being a one of fundamental nature, this relationship
could be viewed as the basic criterion showing the establishment
of a dynamic equilibrium in the biosphere. At
the same time, this provides a reason for investigating
biological carbon cycle processes on the global scale in
more detail. The established regularity offers a new
viewpoint from which the driving mechanism for tremendous
masses of carbon on the earth can be studied.
