no
Most of our oxygen we breathe has been emitted by plants because instead of breathing oxygen and breathing out carbon dioxide, they breathe carbon dioxide and breathe out oxygen as a waste product.
No, but it is safe to breathe. It would just be oxygen.
Mold does not "breathe" in the same way animals do. Instead, mold obtains nutrients through absorbing organic matter from its environment. Mold requires oxygen for growth, but it doesn't "breathe" oxygen in the same way that animals do.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
We breathe oxygen because it is essential for our bodies to produce energy through a process called cellular respiration. Nitrogen, which makes up most of the air we breathe, does not play a direct role in this process.

Try living without Oxygen (to breathe), nitrogen (to dilte the oxygen so that you don't burn up when you breathe), dihydrogen oxide (water that you drink), etc.
so you can get oxygen in your body
Because we don't have gills. We have no way of converting water into oxygen. If you tried to breathe water, you would just drown.
You breathe in oxygen.
Yes you do. See we breathe in oxygen and we breathe out carbon dioxide. Plants are the opposite. They breathe in carbon dioxide and breathe out oxygen. We give them carbon dioxide and they give us oxygen!! That's how we breathe!!!!!!!
On average, humans breathe in about 21% oxygen from the air.
