Figure 3

(a) Illustrative model and (b) concentration distributions. Dark circles are photosynthetic endosymbionts. P stands for photosynthesis, R for respiration, and sw for seawater. In (b), for DIC (red line) and TA (purple line) the calculated ranges of possible concentrations inside the calcifying fluid are provided based on calculations of all species from Supplementary Table 1.
