Instead, as suggested by the trickle - up theory of salmon restoration, the plankton tends to get eaten by tiny animals, which are then eaten by larger animals until, ultimately, all or most of the CO2 sucked up by the tiny plants during their photosynthetic life spans finds its way back to the atmosphere in relatively short order.
