Select one:
a. Cellular Respiration
b. Photosynthesis
c. Both Photosynthesis and Cellular Respiration
d. Neither Photosynthesis nor Cellular Respiration
Heterotrophs undergo cellular respiration in order to turn the food they eat into energy they can use and unlike autotrophs, they cannot make their own energy so photosynthesis isn't required.
