Relative assimilation and respiration of 13C-tracer DOM (left) and bacteria (right). Dark red bars represent relative tracer carbon (CDOM or Cbac) assimilation, light red bars represent relative tracer carbon respiration, as % of total processing of each food source per sponge species tested. HMA high microbial abundance sponge species, LMA low microbial abundance sponge species.
