Final answer:
The arrow that represents cellular respiration in Figure 9-1 is the arrow that points from animals to fossil fuels.
Step-by-step explanation:
The arrow that represents cellular respiration in Figure 9-1 is the arrow that points from animals to fossil fuels.
Cellular respiration is the process by which organisms, including animals and humans, break down organic molecules, such as glucose, to release energy in the form of ATP (adenosine triphosphate).
This process occurs in the mitochondria of cells and is essential for the survival and functioning of living organisms.
