(a–e) Bulk tissue δ¹³C and δ¹⁵N values and C : N for coral hosts and Symbiodiniaceae symbionts and their relative differences (δ¹³C_H–S, δ¹⁵N_H–S) exposed to three Light‐by‐Feeding nutrition treatments and their relation to a pooled plankton sample. Treatments are L–NF (Light–Not Fed, autotrophic), L–F (Light–Fed, mixotrophic), D–F (Dark–Fed, heterotrophic). Boxplots are n = 2, except for plankton (n = 1).
