Figure 1 shows part of a marine phosphorus cycle, including the mass of phosphorus in two major stores.
One teragram (Tg) is 1 × 1012 grams.
The supply of phosphorus to the dissolved ocean phosphate pool is shown as a percentage of the total phosphorus mass of each store.
Calculate in teragrams (Tg) the difference in the supply of phosphorus to the dissolved ocean phosphate pool from the two stores shown in Figure 1.
