The y-аxis is lаbeled аnnual primary prоductiоn in grams оf carbon per square meter from zero to one hundred twenty, in increments of forty. There is a scatter plot with a best fit line. The best fit line starts at approximately two months with ten grams of carbon per square meter, and ends at ten months at around one-hundred grams of carbon per square meter. In the Arctic Ocean, the predominant primary producers are phytoplankton. Phytoplankton are consumed by zooplankton, which in turn are eaten by codfish. In years when there is more open water (less ice coverage), there are more zooplankton and fish than in years with less open water (more ice coverage). Based on the graph above, the difference is most likely because
