  • Steady-state input-output analysis of energy flows in an ecosystem conveniently delineates the discrete steps of energy processing in a given ecosystem. The fraction of a specific flow between species which results from a given input via any integral number of transfers can be calculated. The portions of all flows which are the same number of steps from any external input may, therefore, be aggregated. Furthermore, the mapping which creates these groupings preserves the first and second laws of… CONTINUE READING
