Carbon-Oxygen Cycle
The carbon-oxygen cycle involves four main processes: photosynthesis, respiration, combustion, and decomposition. During photosynthesis, plants take in carbon dioxide and water and release oxygen and energy from sunlight. Respiration is the opposite process, where animals and plants take in oxygen and release carbon dioxide and energy. Combustion releases carbon dioxide into the atmosphere through natural events like volcanoes and the burning of fossil fuels. Decomposition returns carbon and other elements back to the soil and air when organisms die.

- 7. COMBUSTION This isthe process of burning. When combustion occurs, CO2 is released in the atmosphere. Natural combustion includes volcanic eruptions. Most pollution problems occur because cars and factories release CO2 by their burning of fossil fuels.
- 8. COMBUSTION During theCarboniferous Period, large amounts of carbon(in the tissue of plant matter) was trapped underground. Because of lack of oxygen and tremendous pressure, the plant matter was compressed into fossil fuels. Combustion due to fossil contributes to the carbon cycle, which is accelerating the negative effects of global warming.
- 9. DECOMPOSITION When ananimal or a plant dies, all the carbon, oxygen, nitrogen, water, calcium, etc. return to the soil and air during decomposition. Certain insects, fungi, and bacteria aid in the decomposition process and are called decomposers.
