Question

Assume hypothetically that the composition of organic matter produced by phytoplankton would be (CH2)30(CH2O)76(NH3)17(H3PO4)a9

(a) Calculate the C:N:P stoichiometric ratio of this organic matter.

(b) Suppose water upwelling to the surface has a total carbon concentration of 2300 mmol m-3, an oxygen concentration of 160 mmol m-3, a nitrate concentration of 12 mmol m-3, and a phosphate concentration of 1.5 mmol m-3. Which of these nutrients is likely to limit production if the light supply is adequate and if there is no biological nitrogen fixation? Explain.

Explanation / Answer

In the the given formula (CH2)30(CH2O)76(NH3)17(H3PO4)a9. Now in this what does a stand for IN (H3PO4)a9.
