Ocean acidification is considered a significant threat to marine ecosystems primarily because it:

  • A: Directly increases the biodiversity of coral reefs.
  • B: Increases the availability of calcium carbonate for marine organisms.
  • C: Reduces the concentration of carbonate ions needed for calcification.
  • D: Directly increases ocean temperatures, harming cold-water species.

Explanation

The text states: "This is of great concern because carbonate ions are required for calcification, the production of calcium carbonate CaCO3 by many marine organisms, including reef-building corals and animals that build shells."
