A more difficult/longer-term interesting thing to do is to see what biomass components are coming from which carbon source. If you were doing a wet lab experiment, you could label the sources with different isotopes and see where they end up. How do we do the equivalent in FBA? Follow the fluxes? Escher maps would be very useful.
