North American Carbon Program CH. Support long-term quantitative measurements of fluxes, sources, and sinks of atmospheric CO and CH, and develop forecasts for future trends. The North American Carbon Program was designed to help with the process of providing data needed to model the synthesis activities. The carbon cycle is subdivided into two sections, the rapid carbon exchange, and long-term cycling of carbon through the various geological processes. This carbon cycle occurs in our biological processes, including respiration, photosynthesis, and is generated by autotrophs. Autotrophs (usually photosynthetic) are plants or algae, which capture the carbon dioxide from the air. In water, the compounds removed
Carbon dioxide to produce carbonated soft drinks and soda water. Traditionally, the carbonation of beer and sparkling wine came about through natural fermentation, but many manufacturers carbonate these drinks with carbon dioxide recovered from the fermentation process. In the case of bottled and kegged beer, the most common method used is carbonation with recycled carbon dioxide. With the exception of British Real Ale, draught beer is usually transferred from kegs in a cold room or cellar to dispensing taps on the bar using pressurized carbon dioxide, sometimes mixed with nitrogen. Carbon dioxide in the form of dry ice is often used during
