2. Plants & The Carbon Cycle
• Plants take in carbon
dioxide and convert it to
sugar which can be stored
until used for energy.
• This process is called
photosynthesis.
4. Plants & The Carbon Cycle
• Plants release carbon
dioxide as a waste product
when they convert their
stored sugar to chemical
energy.
• This process is called
respiration.
6. Animals & The Carbon
Cycle
• Animals eat carbon
contained in animal and
plant tissues and release
carbon dioxide as a waste
product.
• This process is respiration.
7. Decay & The Carbon Cycle:
• Decomposers release the
carbon from dead plant
and animal tissues back
into the atmosphere.
8. Fossil Fuels & The Carbon
Cycle:
• Over millions
of years fossil
fuels may
form from the
buried
remains of
plants and
animals.
9. Fossil Fuels & The Carbon
Cycle:
• This carbon
reenters the
atmosphere
during
combustion.
10. The Oceans & The Carbon
Cycle:
• Dissolved
carbon
dioxide in sea
water
becomes
deposited as
calcium
carbonate
shells.
11. The Oceans & The Carbon
Cycle:
• Over millions
of years,
these shells
form
sedimentary
rock.
12.
13. • Ocean deposits are the
biggest sink of carbon on
the planet.
• The Rock Cycle ultimately
releases carbon stored in
sedimentary rock.
