This is a diagram of how CO2 breaks down when
combined with H2O to cause ocean acidification
nutrients it needs to preform photosynthesis. This leads to the release or death of the algal symbionts and in turn causes the coral host to parish (1). Along with being in a symbiotic relationship coral also provides an important recycling system to the ecosystem. Healthy coral produces calcium carbonate, and in turn is taken into the new skeleton base for the new growing coral. But since the coral isn’t producing enough calcium carbonate, it cannot replace its self as fast as it is eroding away. This also affects species that depend on that calcium to produce shells.
The shell above is a sea butterfly after the pH level had
been increased to the predicted level of 2010.
