In plants 

Photosynthesis

CO2 + H2O + sunlight -> C6H12O6 + O2

CO2 = Carbondioxide 
H2O = Water
C6H12O6 = Glucose
O2 = Oxygen
In plants and animals

Combustion (cellular respiration)

O2 + C6H12O6 -> CO2 + H20 + energy

CO2 = Carbondioxide 
H2O = Water
C6H12O6 = Glucose
O2 = Oxygen

Where do we need the energy for?
And other animals / plants?
