A. the oxidation of food through the process of cellular respiration

Explanation: Organisms obtain energy by oxidizing organic molecules (like glucose) to produce ATP via cellular respiration (in mitochondria in eukaryotes; in prokaryotes in the cytoplasm/membranes). Autotrophs first capture light energy (photosynthesis) or chemical energy and store it in organic molecules; both autotrophs and heterotrophs then release that stored energy by cellular respiration.
