* All living organisms carry out cellular respiration. It's a fundamental process of life where cells break down glucose (or other energy sources) to produce ATP, the energy currency of cells.

* Food chains illustrate the flow of energy. Plants use photosynthesis to capture energy from the sun. Herbivores eat plants, and carnivores eat herbivores. Each level in the food chain gets energy from the one below it.

Therefore, every organism in a food chain uses cellular respiration, even the plants!
