Schematic illustration of the transfer of metabolites between a photoautotrophic alga (gold) and an organoheterotrophic bacterium (dark grey) embedded in algal extracellular polymeric substances (light grey). The right-hand diagram is an expansion of the area in the box. EPS = extracellular polymeric substances, DOM = dissolved organic matter, VOC = volatile organic compounds, ROS = reactive oxygen species.
