Answer

To find the total uptake of carbon dioxide, we first look at the data from Figure 8 for the time intervals from 11.40 to 13.15 hours.

Assuming the uptake is measured in micromoles per meter squared per hour (μmol/m²/h) and is approximately 5 μmol/m²/h for this interval, we can calculate the total uptake for the area:

Total uptake (μmol) = Uptake per meter squared × Area Total uptake (μmol) = 5 μmol/m²/h × 12000 m² = 60000 μmol

Step 2

Answer

Now, we convert the total uptake calculated into standard form:

60000 μmol = 6.0 × 10⁴ μmol.
