anaerobic respiration
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
Oxygen
Diffusion is a body process that does not require energy from respiration.
Aerobic respiration requires oxygen and Anaerobic respiration does not require oxygen!
oxygen
cellular respiration
Most animals, including humans, require oxygen for respiration. This includes mammals, birds, reptiles, and many invertebrates. Additionally, some bacteria and fungi also require oxygen for their respiration processes.
Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
Animals require higher rate of respiration as they move from one place to another and therefore they need more energy. There the rate of respiration in animals is than in plants. They require more enrgy.
