Soil stores more carbon (C) than all vegetation and the atmosphere combined. C stocks are broadly shaped by temperature, moisture, soil physical characteristics, vegetation, microbial-mediated metabolic processes. The efficiency with which microorganisms use regulates balance between storage in atmosphere. In this review, we discuss how microbial physiology community assembly processes determine growth rate and, turn, organic cycling through lens of ecology. We introduce a conceptual framework cataloging life history (i.e., rate, resource acquisition, stress tolerance) traits competition, facilitation, dispersal) that correspond different efficiencies. also compare dominant mycorrhizal fungal type affects efficiency. propose further development inclusion specific parameters microbial-explicit Earth system models needed for accurately predicting responses to global change.
