 The large variation seen in this simple model suggests that real ecosystems may not obey a single universal relationship between nutrient supply and diversity. To connect to real microbial communities, we validate our growth model against previously published Escherichia coli batch and chemostat experiments and outline potential future experiments to test the model's multispecies predictions .
