||P.31 left column: "In pelagic ecosystems, bacteria process a large
amount of the organic C that enters from either photosynthesis or allochthonous inputs. Among systems,
bacterial secondary production (BP) averages 20 to 30% of planktonic primary production and is as large
as the secondary production of all zooplankton (primary source)."
