Question

Which of the following is the best balance to maintain low levels of carbon dioxide in the atmosphere?

a small volume of plants with a small number of carbon sources
a small volume of plants with a large number of carbon sources
a large volume of plants with a small number of carbon sources
a large volume of plants with a large number of carbon sources

Answer 1

Answer: a large number of plants with a small number of carbon sources.

Explanation: the Formula for photosynthesis is

6CO2 + 6H2O → C6H12O6 + 6O2

So to use the carbon dioxide from the atmosphere to produce sugar and oxygen the more the atmosphere CO2 is available rather than other sources of carbon would allow plants to fully utilize the CO2 in the atmosphere.

a large number of plants would use more CO2 than a small number of plants.
