Solution
The correct option is D Carbon dioxide
Explanation:
(D) Carbon dioxide is a gas that plants require for food production and that mammals exhale during breathing. It is also produced when something burns.
- Plants utilise light and carbon dioxide (CO2) to generate the sugars they need to thrive, releasing oxygen in the process. Photosynthesis is the lungs of our planet.
- Internal respiration is the human body requires carbon dioxide. Internal respiration is a mechanism that transports oxygen to bodily tissues while also transporting carbon dioxide away from them. Carbon dioxide is a protector of the blood's pH, which is necessary for living.
Conclusion: Thus, option (D) is the correct answer.
