D Matrices for trophic (a) and random (b) resource transformations. Each matrix column defines which resources are generated from a given input resource. a, Trophic resource transformations were parameterized by defining resource types (T0, T1, T2, and T3; red lines) which mostly transform into resources of the subsequent type with some self-renewal. b, Random resource transformations were parameterized by defining any resource to transform into any other resource with uniform probability. The colorbar indicates log10 resource transformation rate for a and b. C matrices for trophic (c) and random (d) consumer preferences. Each matrix row defines which resources can be utilized by each consumer. c, Trophic consumer preferences were parameterized by defining consumer families (F0, F1, F2, and G; blue lines) which consume a total of 35 resources of their associated type (for example, F0 consumers utilize T0 resources) and a common resource, T3. G consumers (generalists) consume resources of any type. d, Random consumer preferences were parameterized by defining consumers to utilize any resource with uniform probability. e, Seven initial environmental conditions were defined with 20 resources sampled from (1) T0, (2) T1, (3) T2, (4) T3, (5) T3+T2, (6) T3+T2+T1, and (7) T3+T2+T1+T0. f, Six source communities were defined by sampling 200 consumers.
