Fig. 4From: Bacteriophages affect evolution of bacterial communities in spatially distributed habitats: a simulation studyTrophic graph of the initial community. N1 – non-specific substrate consumed by all populations (P1, P2, P3) of the community. S1, S2, S3 – specific substrates synthesized by corresponding cells. P1 → S 2 P2 means that cells of P1 population produce S2 substrate, which is consumed by cells of P2 populationBack to article page
