Predict the most likely outcome of fertilizing areas of ocean with iron.
A) an increase in dinoflagellate populations that will eliminate problems caused by red tides
B) an increase in foram populations that will contribute to growth of corals and their symbionts
C) an increase in diatom populations that will contribute to reducing atmospheric CO₂
D) a decrease in slime mold populations and thus a decrease in decomposition rates

Question

Quizplus · Accepted Answer

Fertilizing areas of ocean with iron will lead to an increase in diatom populations, which are primary producers that can absorb large amounts of carbon dioxide during photosynthesis. This can contribute to reducing atmospheric CO2 levels. The other options are unlikely outcomes of iron fertilization.
