The identification of inputs and outputs is the first and probably
most important step in testing and analyzing complex systems.
Following accepted natural laws such as the conservation of mass
and the principle of electroneutrality, the input/output analysis
of the system, be it steady or in connection with perturbations
will reveal the status dynamic, will identify whether changes are
reversible or irreversible and whether changing the input will
cause a hysteresis response. Moreover, measurements ofinput and
output fluxes can indicate the storage capacity ofa system, its
resilience to buffer or amplify variations of the external input,
and it can identify structural changes. Therefore, to a certain
extent, the input/output analysis can facilitate predictions about
the ecosystem stability. The measurement of fluxes and the
determination of inputs and outputs of eco systems are, in many
aspects, analogous to measurements done by engineers when testing
an electronic apparatus. The first step is the measurement ofthe
input/output properties of the instrument as a whole, or ofvarious
circuit boards, and the compari. son ofthese with the expected
variations of the original design. Varying input and out. put can
give valuable information about the stability and the regulatory
properties of the device. Nevertheless, only the circuit as an
entity has specific properties which cannot be anticipated if the
individual components are investigated regardless oftheir position.
Also, the instrument as a whole will have different input/output
properties than its subcircuits."
