heterotrophs and increase competition for mineral nutrients, decreasing  nutrients available for photoautotrophs (assuming that heterotrophs  are superior competitors for limiting nutrients as has been observed  \citep[see][Figure~\ref{fig:conceptual}]{COTNER_1992}. \citep[see][Figure~\ref{fig:conceptual}]{COTNER_1992}).  These dynamics should result in the increase in heterotroph biomass relative to the photoautotroph  biomass along a gradient of increasing labile C inputs. We refer to this  differential allocation of limiting resources among components of the microbial
