Answer:
The given blank can be filled with sediments.
Explanation:
The majority of the carbon is stored in the ocean in the form of sediments. These sediments produce from the hard shells and the body components of the marine species, which have captivated carbon in the water. After their death, their bodies move to the deepest part of the ocean, and the tough shell parts get dissociate into sediments that later turn into sedimentary rocks. After getting exposed to water, the acidic carbon gets dissolved and will settle as sediments like calcium carbonate.
