Answer: They use carbohydrate or better known as starch, and they also use lipids to store energy
Explanation: ^^
A graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is graph C.
<h3>The ratio of surface area to volume.</h3>
Generally, the ratio of cell surface area to volume in living organisms is always required to be very small, so as to allow sufficient materials such as food particles, to move through the cell membrane quickly for the cell's survival and optimum function.
When plotted on the cartesian coordinate, a graph which represents the change in cell surface area to volume ratio with an increasing cell diameter is shown in the image attached below.
