Thermodynamic indicators may be denoted as super-holistic indicators because they attempt to quantify by use of one indicator the holistic properties of an ecosystem. In Section 2.8, we presented the thermodynamic indicators eco-exergy, specific exergy = eco-exergy/biomass, power, and emergy. It was discussed how these thermodynamic indicators holistically express the ecosystem properties. The two latter indicators will be presented in detail in Chapter 4, and Chapter 5 will present the ratio of eco-exergy and emergy as an additional super-holistic thermodynamic indicator.
