Study Notes
Carbon Reservoirs
- Carbon reservoir is a storage source for carbon.
- Long-term carbon reservoirs include fossil fuels (oil, coal, natural gas, peat) and limestone.
- Biotic components such as producers, consumers, and decomposers act as short-term carbon reservoirs.
Carbon Compounds in the Oceans
- Large quantities of carbonate and bicarbonate can be found in oceans.
- Calcium carbonate sources include rocks, primarily limestone, and shells of marine organisms.
Fossil Fuel Formation
- Fossil fuels are created through a process called fossilization.
Carbon Cycling Processes
- The process of assimilation cycles carbon through various components in a food web.
Impact of Deforestation
- Deforestation reduces photosynthesis rates, indirectly increasing atmospheric carbon dioxide levels.
Direct Carbon Dioxide Increase
- Cellular respiration by all living organisms contributes directly to the rise of atmospheric carbon dioxide.
- Combustion of fossil fuels results in a direct increase in atmospheric carbon dioxide levels.
Types of Fossil Fuels
- Main fossil fuels include oil, peat, natural gas, and coal.
- Peat can be utilized as soil, while natural gas is primarily composed of methane (CH4).
Carbon Dioxide Information
- Chemical formula for carbon dioxide is CO2.
- Photosynthesis is the only process that removes carbon dioxide from the atmosphere.
- Carbon dioxide contributes to the greenhouse effect by trapping heat.
Carbon Dioxide Management
- Carbon dioxide, produced by cellular respiration, must be released into the atmosphere as it is toxic to living organisms.
Atmospheric Composition
- Carbon dioxide makes up approximately 0.03% of the air.
Essential Terminology
- "Biotic" refers to living organisms.
- All life forms on Earth are considered carbon-based.
- Carbon is a critical component of fats, proteins, nucleic acids, and carbohydrates.
- Detritus is the waste matter and remains of once-living organisms.
- The chemical formula for glucose is C6H12O6.
