The reduction of CO2 to an organic substance, mostly use to produce hexose sugar
1 of 9
Biomass
Total amount of living material per unit area
2 of 9
Respiration
The oxidation of organic substances such as sugar to simpler inorganic compounds such as CO2 with the release of energy
3 of 9
Decay
When animals and plants die releasing CO2 due to the action of microbes breaking down the material
4 of 9
Combustion
Oxidation or organic molecules outside living cells with the formation of CO2 and water
5 of 9
Combustion of Fossil Fuels
Carbon dioxide levels are increasing due to the combustion of fossil fuels, the rising levels of CO2 is linked to Global Warming.
6 of 9
Deforestation
Most mature forests absorb CO2 by photosynthesis the rate CO2 is released back out by respiration - CARBON NEURTAL. If forest was to be cut down in the short term there would be a sharp rise in CO2
7 of 9
Ways CO2 balance is changed
- Volcanoes can increase CO2, carbon dioxide lost by the sea due to the incorporation of carbon into the calcium carbonate skeletons and shells, increase in acid
8 of 9
Biofuels
They are a renewable energy source and is carbon dioxide neutral.
