Question 1

Figure 1 shows part of a marine phosphorus cycle, including the mass of phosphorus in two stores.

Marine Phosphorus Cycle

One teragram (Tg) is 1×10121 \times 10^{12}1×1012 grams.

The annual supply of phosphorus to the dissolved organic phosphorus pool is shown as a percentage of the total phosphorus mass of each store.

Calculate in teragrams (Tg) the difference in the annual supply of phosphorus to the dissolved organic phosphorus pool from the two stores shown in Figure 1.
