Plants absorb carbon dioxide during photosynthesis.
A molecule of carbon dioxide (CO2) has one carbon atom and two oxygen atoms.
Microbes decompose organic waste into a mixture of methane and carbon dioxide.
The increased use of natural gas will help reduce carbon dioxide emissions.
There has been a sudden and worrying rise in the level of carbon dioxide in the atmosphere.
The natural permeability of cellular membranes appears to be important for the survival of the arthropod under low oxygen or high carbon dioxide atmospheres.
This provides flexibility to measure soils with recent manure or compost additions without overwhelming the system with carbon dioxide.
The nature of this greenhouse effect is disputed - the relative roles of sulphur dioxide and carbon dioxide in the greenhouse are strongly debated.
