Best Answer

An autotroph such as a photosynthetic cell produces it's own food. Once produced through photosynthesis, the food needs to be used as in cellular respiration. Hetertroph, such as animals do not produce their own food. They must consume the food produced by the autotrophs or consume the heterotrophs that have consumed the food produced by the autotrophs.

How does cellular respiration depend on photosynthesis?

Aerobic respiration requires oxygen to produce energy and expels carbon dioxide. This ultimately depends on photosynthesis, because plants take the carbon dioxide out of the air and use it for photosynthesis, which expels oxygen into the air as waste.
