Oxygen
The air - what people and animals breathe out etc
People breathe in oxygen and breathe out carbon dioxide. Oxygen is necessary for cellular respiration and provides energy to the body, while carbon dioxide is a waste product of this process that is expelled from the body.
Yes they do. Its part of the carbon cycle. When plants give off carbon dioxide, animals breath it in, when they die, scavengers eat them then decomposer breaks the dead carcasses back into the basic materials.
Carbon Dioxide?
That is correct. People and animals consume oxygen and release carbon dioxide, while plants consume carbon dioxide and release oxygen. It's a match made in heaven.
Neither! Plants breathe carbon dioxide, which is a natural waste product of most animal respiration. I.e., humans and most other animals breathe in oxygen and breathe out carbon dioxide. Plants breathe in carbon dioxide and breathe out oxygen! Which is probably why some people think that it helps to talk to your plant from time to time. (Who knows? It might help it grow a little bit.)
Carbon dioxide
People breath carbon dioxide out of their lungs
Oxygen - we give plant carbon dioxide
Humans breathe in oxygen and exhale carbon dioxide. Plants take in this carbon dioxide along with sunlight and water, and convert it into a form of energy. They release oxygen.Carbon dioxide CO2
People breathe in oxygen, which is essential for their cells to produce energy. They breathe out carbon dioxide, a waste product created by the body's metabolism.
The level of carbon dioxide typically rises in a room over time as people exhale carbon dioxide as they breathe.
