The framings of thermodynamics and empirical observations have led to various theories of how biological systems emerge across different scales of complexity. Power-yield trade-offs span scales from electron transport chains to whole organisms that have been observed to adapt metabolism and adjust their trade-offs in a Pareto efficient manner. Signatures of power-yield trade-offs and strategies for exergy flows exist in microbial genomes, providing opportunities to bridge systems biology, thermodynamics, ecology and evolution. While these principles of power-yield trade-offs have been evaluated for individual microorganisms, to date there are few examples of their application to microbiomes. A natural extension to these theories and observations thus leads us to question how power-yield trade-offs scale from individual microorganisms to microbial communities.
