ANSWER: from plants, plants give of oxygen that we need and we breathe out carbon dioxide(Co2) and that's what plants need
When a plant does phoyosynthesis it lets out oxygen when it is done.
They come from plants. It is a cycle. (Carbon Dioxide and Oxygen Cycle) When you breathe out you realse Carbon Dioxide and the plants sucks it in and relase oxygen and that is what we breathe in.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
The oxygen we breathe comes from the process of photosynthesis in plants, where they convert carbon dioxide and water into glucose and oxygen. The oxygen gas is released as a byproduct of this reaction.
No, they aren't a mammal like a whale or dolphin so they breathe using the oxygen in the water.
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.
animals breathe oxygen, as you know, and exhale carbon dioxide. plants, trees for example, take in carbon dioxide and release oxygen. this is why there is plaenty of oxygen left for every living creature
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide
birds breathe oxygen.
We breathe in oxygen, which is in the form of O2 molecules.
