Which type of organisms are capable of performing cellular respiration?

Cellular respiration is a fundamental process that occurs in both autotrophs and heterotrophs, making the correct answer encompass both categories of organisms.

Autotrophs, such as plants, algae, and some bacteria, perform cellular respiration to convert glucose produced during photosynthesis into usable energy (ATP). They utilize sunlight to synthesize glucose, which then undergoes cellular respiration for energy production even in the absence of light.

Heterotrophs, including animals, fungi, and many bacteria, cannot produce their own food and must consume other organisms to obtain glucose. They also undergo cellular respiration to convert the consumed organic matter into ATP, which sustains their metabolic activities.

Since both groups rely on cellular respiration for energy, the correct answer recognizes the shared capability of both autotrophs and heterotrophs to perform this essential process.
