Essentially, any organism that needs to produce energy to survive uses cellular respiration.
It's important to note that while the overall process of cell respiration is similar across all living things, there are some variations in the specific pathways and mechanisms depending on the organism's type and energy needs. For example, plants use photosynthesis to produce their own energy source, but they still perform cellular respiration to break down that energy for their use.
