When farmers store animal feed, moisture levels need to be kept as low as possible to prevent the growth of fungi. Animal feed was exposed to 10 % moisture and placed into a respirometer. O2 consumption by fungi was monitored using a respirometer over a period of 12 days. The results are shown below.
A specific amount of soda-lime was added to the respirometer before data collection began.
The oxygen consumption rate of the red lionfish (Pterois volitans) was examined in a respirometer at three different water temperatures and at four different body masses.
The experimental set-up used and the results of the experiment are shown below.
Suggest how the oxygen consumption rate of Pterois volitans is determined.
