1. The Carbon Cycle

2. Where is Carbon Found? NEXT Atmosphere Plants Animals Shells Water
Soil
Rocks
NEXT
Fossil Fuels

3. Atmosphere BACK Carbon dioxide is found in the air.
Carbon dioxide is a carbon atom bonded to two oxygen atoms.
BACK

4. Fossil Fuels
Compressed remains of plants and animals that lived millions of years ago
Underground
Coal, oil
BACK

5. Shells BACK Carbon forms the shells of marine organisms.
Shells are made of calcium carbonate, which is calcium bonded to carbon and oxygen atoms.
BACK

6. Rocks BACK Limestone is made of carbonate minerals.
Chalk is made of shells of marine organisms.
Dolomite is calcium magnesium carbonate.
BACK

7. Soil
Soil is made of mineral particles, organic matter, air space, and soil solution.
Soil solution is aqueous liquid consisting of ions, organic matter, or plant roots.
BACK

8. Water BACK Carbon is found in oceans, lakes, and rivers.
Carbon dioxide is dissolved in the oceans.
Carbonate ions can be found in the water.
BACK

9. Plants BACK Plants produce glucose for energy.
Glucose is carbon, hydrogen, and oxygen.
Cellulose is found in the cell walls of plants.
BACK

10. Animals BACK Animals use glucose for energy.
Proteins are used as enzymes, signaling molecules, and structural components.

Fossil Fuels

12. Fossil Fuels BACK Fossil fuels take millions of years to form.
Through heat, pressure, and time, the remains are buried and chemically altered.
BACK

13. Respiration BACK Respiration occurs in both animals and plants.
Organic molecules are changed into carbon dioxide.
Releases energy necessary for metabolic processes
BACK

14. Photosynthesis
Plants use energy from the sun to convert carbon dioxide into glucose.
Glucose can be used for energy.
BACK

15. Decomposition BACK Dead matter is made of complex molecules.
Molecules are broken into simple forms.
Molecules are reused by other organisms.
BACK

16. Consumption
When animals eat plants, carbon within the plant is transferred.
Animals can also get carbon by eating other animals.
BACK

17. Rock Formation and Weathering
Rock particles and organic sediments form flat layers.
Over time, pressure produces rock.
Erosion, or weathering, breaks rocks into particles.
BACK

18. Diffusion BACK Diffusion is molecular mixing.
Carbon dioxide moves into water by diffusion.
Carbon dioxide can move out of the water.
BACK

19. Shell Formation
Animals can use carbon in the water to build shells.
After death, the shells sink.
After physical and chemical change, the shells can be used in sedimentary rocks.
BACK

20. Deforestation
When trees are burned, the carbon contained in them is released as carbon dioxide.
When trees are cut down or burned, photosynthesis cannot take place.
BACK

21. Combustion BACK Fossil fuels are burned to produce energy.
Power cars, generate electricity, make goods
Carbon dioxide is released into the air.
