Answer:
Respiration process
Explanation:
Respiration is simply defined as the biochemical process where the body cells derive their energy from the combination of O₂ and food molecules, and in return liberates CO₂, along with some amount of H₂O and energy. This process elaborates on how the tissue cells help in shifting the O₂ from the exterior air into the cells and in return allows the CO₂ to be released outside.
This process is highly essential for an organism to survive. An organism cannot survive without carrying out this process.
