3. The Carbon Cycle

4. How are plants and cars connected?

5. Inorganic Carbon Dioxide
The Answer is....
CARBON!
Dead plants contain organic carbon which makes fuel
when they are decomposed
Organic Carbon
CH4(CH3)nCH4
Burning fuels releases carbon dioxide,
which plants use to make food (PHOTOSYNTHESIS)
Inorganic Carbon Dioxide
CO2

6. Where do we find Carbon? Carbon is in Everything! Organic Inorganic
Plants and animals (alive or dead)
Fossil fuels
Earth’s soil and rocks (most)
Oceans
Atmosphere (least = 0.03%)
Except for a few asteroids that arrive from space, the amount of carbon on Earth is
constant.
Since there really isn’t any new carbon arriving on Earth, it needs to be in order to change from one form to another.
recycled

7. Because of Recycling...

Photosynthesis in Plants - uses CO2
Eating Plants and Animals - eating Carbon
Cellular Respiration - releases CO2
Decomposition – recycles Carbon
Burning Fossil Fuels - releases CO2
