Carbon Sink
A reservoir that stores more carbon than it releases Ex) ocean, plants, soil
Carbon Sources
Processes that add Carbon into the atmosphere Ex) Fossil Fuel Combustion, Animal Agriculture, Deforestation
Algae & phytoplankton do what
Take CO2 out of the ocean (absorb, carbon sink)
Extraction & Combustion
digging up or mining Fossil Fuels and burning them as energy source (releases CO2 into the atmosphere, carbon source)
Burial
Turns into a carbon reservoir with time and pressure
Fossil Fuels
Coal, Oil, and Natural Gas
Photosynthesis
• Carbon Sink • Removes CO2 from atmosphere and converts it into glucose
Cellular Respiration
• Carbon Source • Done by plants and animals • Uses Oxygen to break glucose down • Releases energy and CO2 into atmosphere
