Effects of CM growth under different configurations and scenarios. “CM photo>phago”—with priority to phototrophy; “CM phago>photo”—with priority to phagotrophy; “CM low PFD”—light provided as 50, rather than the default, 500 μmol m⁻² s⁻¹; “CM prey quantity”—with twice the default prey abundance; “CM prey quantity & quality”—twice the default prey abundance but with prey of half the N:C and P:C. Corresponding changes in P are shown in Supplementary material Fig. S4. [H⁺] is shown for the bulk water; the proximal [H⁺] for a portion of the simulation is shown in Supplementary material Fig. S5.
