HideShow resource information
What is Carbon used in
All organic molecules; Carbohydrates, Fats and Protein
1 of 5
What has caused an increase in CO2? (2)
Burning of fossil fuels - released CO2 previously locked in the fuels. Deforestation - Removed large amount of photosynthesising biomass - Less CO2 is being removed from atmosphere
2 of 5
Main components of Carbon cycle
Release of CO2, Intake of CO2
3 of 5
Releases CO2
Respiration - Animals, plants, microorganisms. Burning fossil fuels. Decomposers - Saprobionts feed on dead material/excretion and ultimately release CO2 from food webs
