Increased carbon dioxide levels are known to increase plant growth. For example, a recent study of wheat has shown that increased carbon dioxide results in a greater crop yield per acre of land. The study controlled for differences in watering, the use of fertilisers, and soil type and quality. The study also found that the increased yield resulting from increased carbon dioxide had a strong negative correlation with the amount of protein and nutritional value of each kilogram of wheat. The researchers hypothesised that the reason for this was because the growth was not accompanied by a similar increase in nutrient intake. In essence, they argued that the yield increased and diluted the protein and nutritional content for each kilogram.
Consider the following incomplete sentence:
As wheat yields increase because of increased carbon dioxide, the
1 decreases because the
2 has not increased.
