According to the law of conservation of matter, matter is not created or destroyed, it only changes form. Once carbon becomes part of the biotic components of the carbon cycle, how does it re-enter the atmosphere? All BUT ONE could apply.
Carbon can re-enter the atmosphere through the following processes:
1. Respiration: When living organisms, including plants and animals, respire, carbon dioxide is released as a byproduct. This carbon dioxide can then be released into the atmosphere.
2. Combustion: When organic matter, such as fossil fuels or vegetation, undergoes combustion (burning), carbon dioxide is produced and released into the atmosphere.
3. Decomposition: When dead organisms or waste materials decay, the process of decomposition releases carbon dioxide into the atmosphere.
4. Volcanic activity: Volcanic eruptions release carbon dioxide and other gases into the atmosphere, including carbon that has been stored in rocks or magma.
The option that does not apply is:
5. Photosynthesis: Photosynthesis is the process by which plants convert carbon dioxide into organic carbon compounds, such as glucose. It does not involve the re-entry of carbon into the atmosphere.
