** <B>Carbon dioxide</B> ([[chemical formula]] <B>CO<sub>2</sub></B>) is a naturally occurring [[chemical compound]] composed of 2 [[oxygen]] [[atom]]s each [[covalent bond|covalently]] [[double bond]]ed to a single [[carbon]] atom. It is a [[gas]] at [[standard temperature and pressure]] and exists in [[Earth's atmosphere]] in this state, as a [[trace gas]] at a concentration of 0.04 per cent (400 [[Parts per million|ppm]]) by volume, as of 2014.<ref name=NOAA>National Oceanic and Atmospheric Administration (NOAA): http://www.noaa.gov/</ref> <P> As part of the [[carbon cycle]], [[plant]]s, [[algae]], and [[cyanobacteria]] use [[light]] [[energy]] to [[photosynthesis|photosynthesize]] [[carbohydrate]] from carbon dioxide and [[water]], with [[oxygen]] produced as a waste product.  However, photosynthesis cannot occur in darkness and at night some carbon dioxide is produced by plants during [[Cellular respiration|respiration]]. <ref> [http://www.legacyproject.org/activities/foodfactories.html Food Factories]. www.legacyproject.org. Retrieved on 2011-10-10. </ref> It is produced during the respiration of all other [[aerobic organisms]] and is exhaled in the breath of air-breathing land animals, including humans. Carbon dioxide is produced during the processes of [[decomposition|decay]] of organic materials and the [[fermentation]] of sugars in [[beer]] and [[wine]]making. It is produced by [[combustion]] of [[wood]], [[carbohydrate]]s and major [[carbon]]- and [[hydrocarbon]]-rich [[fossil fuel]]s such as coal, peat, petroleum and natural gas. It is emitted from [[volcano]]es, [[hot spring]]s and [[geyser]]s and is freed from [[carbonate rock]]s by [[dissolution (chemistry)|dissolution]] in water and acids. CO<sub>2</sub> is found in lakes, at depth under the sea and commingled with oil and gas deposits.  The environmental effects of carbon dioxide are of significant interest. Atmospheric carbon dioxide is the primary source of carbon in [[life]] on Earth and its concentration in Earth's pre-industrial atmosphere since late in the [[Precambrian]] eon was regulated by [[photosynthesis|photosynthetic]] organisms. Carbon dioxide is an important [[greenhouse gas]] and burning of carbon-based fuels since the [[industrial revolution]] has rapidly increased its concentration in the atmosphere, leading to [[global warming]]. It is also a major source of [[ocean acidification]] since it dissolves in water to form [[carbonic acid]]. <ref> National Research Council. "Summary."
