Correct answer: "Plants remove carbon from the atmosphere to help them make glucose."
Explanation: Through photosynthesis plants take in atmospheric CO2 and use the carbon to build glucose and other organic molecules. This carbon fixation is a key step in the carbon cycle, transferring inorganic carbon into living biomass that fuels food webs and stores carbon until it is returned by respiration, decomposition, or combustion. Plants do not take carbon from the soil to make glucose, nor do they convert atmospheric carbon to convert nitrogen (nitrogen fixation is done by certain bacteria).
