An economic analogy for ecosystems analysis is proposed. Adapting static and dynamic input-output theory to model the energy flowing through ecosystems allows some unusual insights. For example, the total system energy input needed to produce a top carnivore can be calculated by slightly perturbing the steady state (static modeling) or by a dynamic model. The results are quite different. If the ecosystem is not preconditioned by a specific set of controlled flows, the response of the dynamic model to a perturbation is unstable.
