Where does Carbon come from?
Carbon Dioxide in the Air
CO 2 is taken out of the air by plants through photosynthesis.
Animals can’t go through photosynthesis so they get their carbon atoms from food they eat.
BOTH plants and animals release CO 2 into the air through respiration
Decaying plants, animals, and waste after millions of years will be changed into fossil fuels
Fossil fuels can be burned by automobiles, releasing carbon back into the atmosphere
Carbon dioxide in the atmosphere Burning of fossil fuels in cars and factories release carbon dioxide Photosynthesis removes carbon dioxide from the air. Cellular respiration releases carbon dioxide into the air Decaying organisms changing into fossil fuels.
