Decomposition
dead
organic matter is
broken down
by organisms called decomposers (bacteria + fungi)
How is glucose is broken down?
By the decomposers in the process of respiration.
Fossilisation
dead
organic matter can't decompose (lack of O

) over millions of years it forms into fossil fuels (oil, coal, gas)
Combustion
burning of fossil fuels
What do fossil fuels contain?
Carbon
Word Equation of Combustion
(fossil) fuel + oxygen --> carbon dioxide + water + energy
