FIG 1.

rRNA amplification and random assignment of cells to metabolic states. Three different rRNA amplification models were used to represent variation in the abundance of ribosomes in cells in four metabolic states. The number of ribosomes per cell in each of the activity metabolic states with the different rRNA amplification models is indicated. Data for the rRNA amplification models were based on data from Table S1. For simulations, each population in a community represented a mixture of cells in different metabolic states. The number of cells in a given population was determined from a community structure model. The cells in a population were randomly assigned to four metabolic states, and the net activity status of each population was calculated.
