mesozooplankton (which include fish larvae), though as consumers of organic mater-
ial heterotrophs obviously include the fish, marine mammals and ultimately the top
predator of them all, we humans. Our focus on the smaller end of the heterotrophic
size range is predicated on identifying the organisms that are most likely to be at the
mercy of turbulence and flows in the ocean. Figure 5.13 illustrates a few of the many
diverse many heterotrophic organisms.
