Question

In which zone are plankton plentiful, providing plenty of food for the fish that live there?

Answer 1

Phytoplankton are scarce in remote ocean gyres due to nutrient limitations. Phytoplankton are most abundant (yellow, high chlorophyll) in high latitudes and in upwelling zones along the equator and near coastlines. They are scarce in remote oceans (dark blue), where nutrient levels are low.
