The process through which animals take oxygen (O2) from the air and release carbon dioxide (CO2) into the air is called:
Correct answer: A. Breathing
- A. Breathing
- B. Respiration
- C. Diffusion
- D. Osmosis
Explanation
The process through which animals take oxygen (O2) from the air and release carbon dioxide (CO2) into the air is called "Breathing". It can't be "respiration" because, in cellular respiration, glucose is broken down to give energy. It can't be "diffusion" or "osmosis" as it involves the movement of substances through a concentration gradient.The animals breathe in oxygen and breathe out carbon dioxide in the process of respiration. Respiration is the process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
