Carbon Cycle
Points to note - - Usually, carbon does not exist alone. It forms molecules or compounds. E.g. it can exist as CO 2 and it is also a component of protein, lipids carbohydrates that found in living organisms - - Carbon enters the Carbon cycle through photosynthesis when plants, algae or some bacteria use carbon dioxide to manufacture food. - - Glucose made, contains carbon (C 6 H 12 O 6 ). The carbon is also used to make plant proteins, and lipids. Therefore, when animals feed on plants, the carbon is transferred to the animals - - Plants and animals undergo respiration, and the glucose (C 6 H 12 O 6 ) breaks down. Carbon Dioxide (CO 2 ) is then released into the atmosphere - - When animals and plants die, or release waste, then microorganisms will feed on the waste, and release...
