Question

Which one is not the dynamic aspect of an ecosystem?

Answer 1

Ecological dynamics models, input–output analysis models, and ecological network models simulate the evolution of metabolic processes, the factors that influence them, and the system's internal operating mechanisms. Ecological dynamics models are an important tool for simulating flows of materials and energy in an urban metabolism because rapid advances in computer technology have made such complex simulations feasible. These models combine system dynamics methods with material accounting and emergy indicators by analyzing the system's composition and structure and the causal mechanisms responsible for flows through the system. A model of the evolution of the system's ecological thermodynamic properties and processes can be constructed, and will allow prediction of long-term dynamic changes in the system's metabolic processes. Input–output models can be used to account for all inputs into and outputs from a system. As this accounting becomes increasingly precise, it allows the development of input–output tables for the actors in the urban metabolic processes, and therefore allows simulation of the direct and indirect effects of the actors.
