when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide
its what you breathe and what plants breathe out while they breathe that out they breathe in carbon diOxide and we breathe it out.
Carbon Deoxide
We Breathe in a mixture of Carbon, Hydrogen and Oxygen, and exhale Carbon Dioxide
We breathe in oxygen and breathe out carbon dioxide.
Plants breathe in carbon dioxide and breathe out oxygen; animals breathe in oxygen & breathe out carbon dioxide.
Well plants breathe in Carbon Dioxide and breathe out Oxygen. We breathe in the oxygen and breathe out Carbon Dioxide. So its like a cycle.
Penguins breathe in oxygen and breathe out carbon dioxide. They have this in common with all animals.
trees breathe out oxygen we breathe out carbon dioxide and trees breathe in carbon dioxide SAVE THE RAINFORESTS OR WE'LL DIE!!
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.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
For We can Breath In Carbon Dioxide. :)We do not breathe in carbon dioxide (CO2), we actually breathe in oxygen, and let out carbon dioxide, which trees use to breathe.
