Simulation results for the resource competition model (dots) and analytical predictions in the disordered limit (lines) for various community properties: (A) total biomass $T$, (B) fraction of surviving species $\varphi$, (C) Simpson diversity $D$, and (D) temporal variability $V$. We vary the number of resources $R$ and the heterogeneity of consumption rates ${\sigma }_{\xi }$ (see Materials and Methods). This then affects the value of the generic parameters in Eq. 3, inserted into the analytical solution of the reference model to obtain null predictions. The remarkable agreement confirms that the resource competition model exhibits fully disordered behavior.
