Learning Objective
I can describe how living and non-living things interact in a coral reef ecosystem.
- 1
Stony corals create the foundation of the reef by forming stone skeletons from calcium carbonate.
- 2
Soft corals and sponges attach to the hard surfaces created by stony corals, adding complexity and color to the reef.
- 3
Herbivorous and corallivorous fish help maintain the reef's structure by eating algae and coral.
