Detailed explanation-1: -Cellular respiration occurs in the cells of all living things. It takes place in the cells of both autotrophs and heterotrophs. All of them burn glucose to form ATP.

Detailed explanation-2: -All organisms carrying out photosynthesis require sunlight. Heterotrophs are organisms incapable of photosynthesis that must therefore obtain energy and carbon from food by consuming other organisms.

Detailed explanation-3: -Heterotrophs are required to consume other organisms or parts of organisms in order to obtain their food molecules. They undergo cellular respiration in order to turn the food they eat into energy they can use.

Detailed explanation-4: -Yes, autotrophs need to carry out cellular respiration. It is a necessary process to convert the glucose cells consumed into energy used by the cell to move, grow, and reproduce. If the cellular respiration occurs using oxygen, then it is aerobic respiration.
