We do. It's virtually the only source (You're breathing it right now, I hope).
Oxygen is the gas in the atmosphere that is essential for human life. Our bodies use oxygen to generate energy through the process of respiration. Without oxygen, humans would not be able to survive.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
Most animals, including humans, use oxygen for respiration. This process involves taking in oxygen from the atmosphere and using it to break down food molecules to produce energy.
The plant put back oxygen into the atmosphere and the humans (us) use the oxygen to breathe Oxygen is used by all living things as well as playing a part in oxidization Fire corrosion etc
No, humans do not use or consume 60 percent of the oxygen on Earth. The atmosphere is made up of about 21% oxygen, and human respiration accounts for only a small fraction of that.
the use of fossil fuels by humans had tainted the air and atmosphere
Oxygen is a gas that does not naturally replenish itself in the atmosphere and requires the work of photosynthesizing plants to replenish it. Humans breath oxygen that plants produce and the plants breathe the carbon dioxide that humans produce.
The most important product of the light reaction in plants for humans is oxygen. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Oxygen is released into the atmosphere as a byproduct of this process and is essential for human respiration.
Humans disrupt the carbon cycle by burning fossil fuels, releasing excess carbon dioxide into the atmosphere. This disrupts the natural balance of carbon stored in the atmosphere, oceans, and land. Likewise, deforestation and land-use changes can disrupt the oxygen cycle by reducing the number of trees that absorb carbon dioxide and release oxygen during photosynthesis.
In the light reaction of photosynthesis, oxygen is produced as a waste product. This oxygen is released into the atmosphere and is essential for humans as we breathe it in during respiration.
the advantage of micro organisms is that they help to keep the balance in the atmosphere. micro organisms use nitrogen like humans use oxygen, so nitrogen is 71% in the atmosphere and oxygen 21% and carbon dioxide 0.04% so with the help these of organisms there is a balance in the air that's why they are called important
Terrible grammar. Either the asker does not speek English or is mentally challenged. I will slowly answer this question the best that I can. Humans... use oxygen... to breathe... If humans could not breathe they could not do anything industrial! That is "how humans you use oxygen in industry". They breathe it. You should try it. Your brain could use some oxygen numbnut!
