A study in wheat fields showed that high levels of carbon dioxide in the atmosphere impair the absorption of nitrate by plants. Consequently, the nutritional quality of these foods may decrease as the levels of carbon dioxide in the atmosphere reach estimates for the coming decades. In this context, the nutritional quality of the wheat grain will be modified primarily by reducing which element?
