Answer to Question 1

C

Answer to Question 2

The magnitude of the biological pump, as controlled by nutrient availability (including Fe) could have led to a positive feedback look on glacial-interglacial timescales. Growth of coral reefs as sea-level rose and flooded the tropical continental shelves during deglaciation would have released CO2 to the atmosphere, furthering the warming and ice-sheet melting.
