What would occur with increased calcification in marine ecosystems?

Increased calcification in marine ecosystems primarily leads to enhanced shell production among calcifying organisms such as mollusks, corals, and some types of plankton. This process occurs because calcification involves the deposition of calcium carbonate, which is essential for forming shells and skeletons. As ocean conditions change, particularly with elevated levels of carbon dioxide affecting water chemistry, organisms that rely on calcium carbonate may respond positively if the availability of calcium and other necessary ions is sufficient.

Calcifying organisms are essential to marine ecosystems because they form structural habitats (like reefs) that support a diverse array of marine life. Enhanced shell production not only aids in the survival and growth of these organisms but also contributes to the overall health and stability of the marine ecosystem. Healthy populations of calcifying species can improve habitat complexity, which supports increased species richness and biodiversity.

While increased calcification is beneficial for specific organisms, it must be considered alongside overall ocean health and conditions, including factors such as temperature and acidity.
