4.9 describe the stages in the carbon cycle, including respiration, photosynthesis, decomposition and combustion

Respiration is carried out by animals and plants to release energy from glucose, the equation is:
C6H12O6 + 6O2    →    6CO2 + 6H2O . This means carbon is produced.

Photosynthesis is what plants do to create glucose the equation is:
6 CO2 + 12 H2O → C6H12O6 + 6 O2 + 6 H2O. This means carbon is used.

Decomposition is happens when an animal dies, it is then eaten by a decomposer which releases the carbon in it back into the atmosphere.

Combustion is burning, if something with carbon is burnt it will release it into the atmosphere, e.g. a tree, fossil fuel.

This is one of many useful diagrams:
