Sagot :

Inhale oxygen and exhale carbon dioxide

The carbon dioxide breathed in out is a result of the course of cell breath, as is water. In this cycle, energy is made in the mitochondria of cells. This energy is our physical "life power". Both oxygen and glucose are needed for this. Glucose contains carbon. That is the place where the carbon in carbon dioxide comes from. Glucose notwithstanding oxygen produces carbon dioxide, water and energy. Exactly when this cycle stops, the cell fails miserably.

Trees and plants transmit carbon dioxide when they breathe in, and when they pass on and rot. We take in oxygen and a part of this carbon dioxide. Right when we inhale out, we breathe in out less oxygen anyway more carbon dioxide than we take in.
