We need to share with other humans, plants, and animals.
Humans are anmals and we all act alike in that we need to take in oxygen in the air.
when you breath in throught the nose all of that oxygen from the air comes from the oxygen and carbon dioxide that other people breath in.
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
Yes. All gasses take up space and can therefore displace oxygen.
The leaves supply almost all of the oxygen, so through the air.
Yes. You take in air which is about 20% oxygen
All over the body. Think your toes don't need air?
All I can say is that when you breath in, you take in air and extract the oxygen. When you exhale you're letting out the nitrogen that was with the oxygen in the air. The oxygen then goes to your blood. How this happens? I can't say. Sorry.
They extract oxygen from the air.
The group of organs that take in oxygen from the air is called your respiratory system.
When you inhale (take in air when you breathe), you are taking in Oxygen.
we take in oxygen via the air. the air is made up of 21% oxygen and oxygen is produced by many things. our lungs intake the air. through the mouth and nose.
