4.9- Carbon Cycle

                                            
1) Photosynthesis:

• CO2+H20------>C6H12O6
• reduces carbon dioxide in the atmosphere

2) Feeding:

• Carbon passes along the food chain

3) Respiration:

• Aerobic: C6H12O6 + O2----->CO2+H20+ Energy
• Adds CO2 to the atmosphere
• All organisms are giving off carbon dioxide to the atmosphere through respiration 

4)Decomposition: 

• Organic molecules are broken down by the decomposer organisms which includes bacteria and Fungi
• This will result in the release of carbon dioxide back to the atmosphere

5) Combustion:

• Fossil fuels (Oils and coals)------------> Carbon dioxide 
• Industrial uses can contribute the amount of carbon dioxide in the motor vehicles
• Combustion can occur naturally ( forest fires)
