It was excretion. Respiration is a metabolic reaction, but it's not how you get rid of the waste products of metabloic reactions. To get rid of the waste products of respiration you have to excrete CO2 and H2O.
Well done :D
Steve13:
Excretion is to remove organisms of toxic
materials, the waste products of metabolism
(chemical reactions in cells including
respiration) and substances in excess of
requirements
Respiration as the chemical reactions that
break down nutrient molecules in living cells
to release energy
