Question

An organism that requires oxygen.

Answer 1

An organism that requires oxygen for its metabolic processes is known as an aerobic organism. These organisms rely on oxygen to break down substrates, such as glucose, to produce energy through cellular respiration. Examples of aerobic organisms include humans, other mammals, birds, most reptiles, many insects, and many types of fungi and bacteria. In contrast, anaerobic organisms can thrive in environments without oxygen, using different methods to obtain energy.
