Questions and Answers
Explain the processes through which carbon dioxide enters and returns to the atmosphere.
Carbon dioxide enters living tissues through photosynthesis, respiration, and combustion. It returns to the atmosphere through the same processes.
Where is most of the earth's carbon stored and how is it stored there?
Most of the earth's carbon is stored in fossil fuels, which are created from the compression of organisms that have died over millions of years.
