Questions and Answers

What role does the increasing entropy play in thermodynamics regarding biological life?

  • It implies a reduction of energy exchange in ecosystems.
  • It results from the decreasing free energy. (correct)
  • It results from an increase in free energy.

    Maximal energy dispersal

    A universal principle that explains species-area relationships, driven by the tendency of energy to spread maximally.

    Free energy/Exergy

    The energy difference driving transformations in natural systems (e.g., ecosystems, chemical systems).

    Ecological succession

    The process of changes in ecological communities over time, following from the principle of maximal free energy reduction and least action.

    Distinguishable species

    Two species are distinguishable if their interactions lead to dissipation of energy (dissipative).

    Open Systems Thermodynamics

    The thermodynamics of systems that exchange energy and/or matter with their surrounding, such as biological systems. These exchanges lead to specific order/disorder outcomes
