carbon dioxide, n.All

Carbon dioxide is no poison to plants and organisms that make shells or coral. For them it is a building block.

Mosquitoes can detect carbon dioxide from 75 feet away. In fact that's how they find their victims.

Our urge to breathe is not because of our need for oxygen but our bodies wanting to get rid of carbon dioxide.

When humans lose weight, about 80% of the fat is converted into carbon dioxide and exhaled through the lungs.
