What is the main difference between respiration and breathing?
Answer and explanation
Correct answer: Respiration is the chemical release of energy and breathing is the movement of gases in and out
The governing concept is that breathing and cellular respiration are related but different stages of gas use. Breathing is the physical movement of air into and out of the lungs, whereas respiration is a chemical process inside cells in which food, usually glucose, is broken down to release usable energy. Therefore option A is correct; the other options confuse respiration with digestion, excretion, or plant organ functions.
