Total inorganic carbon is not believed to limit primary production in the oceans, so its increasing availability in the ocean does not directly affect production ( the situation on land is different, since enhanced atmospheric levels of CO < sub > 2 </ sub > essentially " fertilize " land plant growth ).

In terms of measurement, four basic parameters are of key importance: Total inorganic carbon ( TIC, T < sub > CO2 </ sub > or C < sub > T </ sub >), Total alkalinity ( T < sub > ALK </ sub > or A < sub > T </ sub >), pH, and pCO < sub > 2 </ sub >.

Total inorganic carbon is typically measured by the acidification of the sample which drives the equilibria to CO < sub > 2 </ sub >.

* Total Carbon ( TC ) – all the carbon in the sample, including both inorganic and organic carbon

* Total Inorganic Carbon ( TIC ) – often referred to as inorganic carbon ( IC ), carbonate, bicarbonate, and dissolved carbon dioxide ( CO < sub > 2 </ sub >).

Total emissions from the worldwide 500, 000 km < sup > 2 </ sup > of degraded peatland may exceed 2. 0 Gtons ( including emissions from peat fires ) which is almost 6 % of all global carbon emissions.

* Total organic carbon, often used as a non-specific indicator of water quality

Total organic carbon ( TOC ) is the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.

The most common oxidation state of carbon in inorganic compounds is + 4, while + 2 is found in carbon monoxide and other transition metal carbonyl complexes.

The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil and methane clathrates.

Dissolved CO < sub > 2 </ sub >, along with carbonate and bicarbonate ions, are referred to as dissolved inorganic carbon ( DIC ).

This role as a sink for CO < sub > 2 </ sub > is driven by two processes, the solubility pump and the biological pump .< ref > The former is primarily a function of differential CO < sub > 2 </ sub > solubility in seawater and the thermohaline circulation, while the latter is the sum of a series of biological processes that transport carbon ( in organic and inorganic forms ) from the surface euphotic zone to the ocean's interior.

; Lithoautotroph: An organism ( usually bacteria ) whose sole source of carbon is carbon dioxide and exergonic inorganic oxidation ( chemolithotrophs ) such as Nitrosomonas europaea ; these organisms are capable of deriving energy from reduced mineral compounds like pyrites, and are active in geochemical cycling and the weathering of parent bedrock to form soil

Primary production is the production of organic matter from inorganic carbon sources.

Although heterocyclic compounds may be inorganic, most contain at least one carbon.

Organic carbon compounds are more abundant than inorganic carbon compounds.

The known inorganic chemistry of the allotropes of carbon ( diamond, graphite, and the fullerenes ) blossomed with the discovery of buckminsterfullerene in 1985, as additional fullerenes and their various derivatives were discovered.

There is a rich variety of carbon chemistry that does not fall within the realm of organic chemistry and is thus called inorganic carbon chemistry.

Important inorganic carbon-sulfur compounds are the carbon sulfides carbon disulfide ( CS < sub > 2 </ sub >) and carbonyl sulfide ( OCS ).

For historical reasons discussed below, a few types of carbon-containing compounds such as carbides, carbonates, simple oxides of carbon ( such as CO and CO2 ), and cyanides, as well as the allotropes of carbon such as diamond and graphite, are considered inorganic.

The distinction between " organic " and " inorganic " carbon compounds, while " useful in organizing the vast subject of chemistry ... is somewhat arbitrary ".

Even the broader definition of " carbon-containing molecules " requires the exclusion of carbon-containing alloys ( including steel ), a relatively small number of carbon-containing compounds such as metal carbonates and carbonyls, simple oxides of carbon and cyanides, as well as the allotropes of carbon and simple carbon halides and sulfides, which are usually considered to be inorganic.

Phytoplankton use photosynthesis to convert inorganic carbon into protoplasm.
