Comments This value is in contrast to the fact that primary producers in the ocean are responsible for nearly half of the biospheric NPP (see bion 102937 )This uncoupling between NPP and biomass is a consequence of the more than three orders of magnitude faster turnover time of plant organic matter in the oceans (average 2 to 6 days) (ref 1 in article) than on land (average 19 years) (ref 42 in article).
