Question

1. what types of organisms perform cellular respiration?

Explanation:

Cellular respiration is a fundamental metabolic process. It occurs in organisms that need to generate energy (in the form of ATP) from organic molecules. Most living organisms, including animals (heterotrophs that consume organic matter), plants (autotrophs that can produce their own organic matter via photosynthesis but still need to break it down for energy), fungi (heterotrophic decomposers or symbionts), and many types of bacteria (both autotrophic like some chemosynthetic bacteria and heterotrophic bacteria) perform cellular respiration. The process can be aerobic (using oxygen as the final electron acceptor) or anaerobic (using other molecules like sulfate or nitrate as final electron acceptors in some bacteria).

Answer:

Most living organisms, including animals, plants, fungi, and many bacteria, perform cellular respiration.
