You are making CO2 production measurements on hovering hummingbirds in Peru and assume they have fed on floral nectar recently (glucose), but in fact, they have not fed in the last hour and are metabolizing fat; given this incorrect assumption - by approximately what error (%) will you over or underestimate their metabolic rate? Metabolic RQ of Carbohydrate digestion is 1: fat digestion:.7
