Final answer:
In a respirometer experiment, it is important to keep the apparatus at a constant temperature to ensure accurate and reliable measurements of the oxygen consumed by organisms. changes observed in the volume of oxygen consumed can be attributed to the activity of the organisms rather than temperature fluctuations.
Step-by-step explanation:
In a respirometer experiment, it is important to keep the apparatus at a constant temperature to ensure that the measurements are accurate and reliable. This is because temperature affects the rate of respiration in organisms. As temperature increases, the rate of respiration also increases, and vice versa. By keeping the apparatus at a constant temperature, any changes observed in the volume of oxygen consumed can be attributed to the activity of the organisms rather than temperature fluctuations.
