Important for humans because lies over continental shelf lies beyond continental shelf provides food and livelihood for regulates climate and atmosphere.

Prochlorococcus most abundant and dominant in nutrient poor tropical1subtropical waters. Trichodesmium grows in filamentouscolonies abundant in nutrient poor waters fixnitrogen. Zooplankton primary consumers most are carnivorous consuming herbivorous zooplankton.
