Although the vast majority of marine fishes are carnivores, in near-surface regions of high productivity the concentrations of larger phytoplankton (the plant component of plankton) are sufficient to support huge populations of filter-feeding sardines and anchovies. These small fishes use their gill ...
What else? The Sun's energy is more intense near the equator than it is near the poles, so you've got masses of warmer air over the equatorial regions, and masses of cooler air over Polar Regions. And these masses are constantly interacting with each other, which is critically important ...
