The circulation of carbon in ecosystems with the manufacturer's plants is important. The plants use carbon in the form of carbon dioxide to create food by photosynthesis. When herbivores Carbon will accumulate in the tissues When plants and animals die The decomposition of organic matter will decompose fossil. And fuel combustion are carbon back into the atmosphere there. In addition, the carbon dioxide in the atmosphere can be dissolved. Water plants used as raw material for photosynthesis. When carbon dioxide mixes with water, some of the compounds may have hydrogen carbonate. In the water, the water will naturally dissolve calcium is always. Which can react with hydrogen sulfide, carbonate and limestone, and limestone, causing it to break apart the carbon bot net. Once in the acidic environment
