Question

respiration and combustion use _ from the air​

Answer 1

Answer:

Respiration and combustion use oxygen from the air.

Explanation:

Oxygen is crucial for the respiration of living organisms, and it helps combustion because it is crucial for burning components. The lungs and respiratory system allow us to breathe and they carry oxygen into our bodies and send carbon dioxide out. So this exchange of oxygen and carbon dioxide is called respiration or breathing. During combustion, oxygen in the atmosphere reacts with the carbon atoms to produce carbon dioxide and hydrogen atoms to produce water

Answer 2

Oxygen is used in both respiration and combustion.

Explanation:

• Living creatures require oxygen for breathing, and it also aids combustion since it is required for the combustion of components.
• The lungs and respiratory system allow us to breathe and transport oxygen into and out of our bodies.
• Respiration (or breathing) is the process of exchanging oxygen and carbon dioxide.
• During combustion, oxygen in the atmosphere combines with carbon atoms to form carbon dioxide, while hydrogen atoms react with carbon atoms to form water.
