“…Erwin Schrödinger (1887-1961) highlighted negative entropy as a capacity of producing order out of disorder [9]. Negentropy is a thermodynamic phenomenon that leads to higher efficiency; nevertheless, the absolute magnitude of general efficiency cannot be determined due to the countless biotic and abiotic interactions in the ecosystem [12]. The equilibrium between biotic and abiotic structures is evolving during the earth's life and it generates entropy increment in some structures while it makes orders in others (negative entropy) [13]; In other words, Negentropy might be characterized as the stored energy in a highly structured system in terms of space and time.…”

In this chapter, the various terms of entropy generation in terrestrial systems and the atmosphere are estimated by imitating the entropy analysis of a steam power generation (STPG). The highest entropy generation is associated with the outgoing longwave radiation flux (more than 20–200 times the downward solar radiation). The results indicate that the most significant terms of entropy generation (heat dissipation) in different processes are related to latent and sensible heat fluxes (similar to steam generation and flue gas of the STPG). The vegetation cover (boiler system) destroys a part of solar energy absorption in the form of entropy generated by the formation of water vapor and transpiration (steam turbine). Given that life is formed by the optimal balance between the system, the ecosystem, and the living and nonliving organisms, it is important to study the various entropy fluxes in ecosystems that can lead to ecosystem balance.
