Study Notes
Carbon Cycle
- Carbon is stored in Earth's reservoirs, including rocks, oceans, atmosphere, plants, soils, and fuels.
- Carbon continuously flows between these reservoirs.
- The carbon cycle has fast and slow components.
- Fast processes involve living organisms.
- Slow processes involve rocks, soil, and fossil fuels.
- Changes in the carbon cycle impact the Earth's temperature.
Steps of the Carbon Cycle: Fast Process
- Photosynthesis: Plants absorb carbon dioxide (CO2) and convert it into sugars and tissues.
- Respiration: Animals and decomposers inhale CO2 for respiration and release it back into the atmosphere.
- Burial and Sedimentation: Some carbon is buried and forms rocks or fossil fuels over millions of years.
- Extraction: Humans extract fossil fuels from the Earth.
- Combustion: Humans burn fossil fuels, releasing CO2 back into the atmosphere.
- Exchange with the Ocean: Carbon is constantly exchanged between the ocean and the atmosphere.
Other Important Notes
- A significant amount of carbon is exchanged between the ocean and the atmosphere.
- CO2 diffuses into the ocean, forming carbonic acid, which can lead to ocean acidification if CO2 concentrations are too high.
- Algae perform photosynthesis, converting carbon into sugars.
- Some carbon is stored as sediment on the ocean floor.
Carbon Cycle: More Information
- Combustion converts fuels and plant materials into carbon dioxide.
- CO2 constantly exchanges between the atmosphere and water.
Carbon Cycle Steps: Breakdown
- Producers: Organisms like plants convert CO2 into sugars through photosynthesis.
- Sugar Conversion: Sugars are converted back into CO2 through respiration or decomposition.
- Carbon Burial: Some carbon gets buried and forms sedimentary rocks.
- Fossil Fuels: Humans extract fossil fuels from the Earth.
