Every relation drawn, in words3
- Reef-building corals (Scleractinia) · depends_on · Zooxanthellae (Symbiodiniaceae)
Reef-building corals derive the majority of their energy budget from carbon fixed by symbionts living in their tissue, which is what allows them to build large structures in nutrient-poor water.
- Zooxanthellae (Symbiodiniaceae) · displaced_from · Reef-building corals (Scleractinia)
Bleaching is the loss of the symbionts from host tissue: the host expels them, or they lose their pigments, leaving the white skeleton visible through transparent tissue.
- Zooxanthellae (Symbiodiniaceae) · supplies · Coral calcification
Calcification is light-enhanced because the energy for the ion pumping that drives aragonite precipitation comes substantially from symbiont photosynthesis.
