The early experiment by Van Helmont (1600s) describes how he grew a tree in a large pot and found that after five years, the amount of soil in the pot had not changed. He concluded that the increase in weight was due to the addition of water. At that time, the compounds in air had not yet been identified. Today, you know that he only discovered half the story. Which additional experiment would provide evidence for the rest of the story?
A. A very careful measurement of the water taken in and lost by the tree would have revealed only half the added weight gained by the tree was from water. B. Analysis of nutrients in the soil would account for half the weight of the tree. C. Carbon is discovered as a major element in trees and is lacking in water molecules. D. Radioactive carbon in carbon dioxide in the air is identified as part of the tree structure. E. All of the experiments but for an analysis of nutrients in the soil would account for half the weight of the tree.
