  abstract = {{M}esozooplankton play a key role in marine ecosystems as they modulate the transfer of energy from phytoplankton to large marine organisms. {I}n addition, they directly influence the oceanic cycles of carbon and nutrients through vertical migrations, fecal pellet production, respiration, and excretion. {M}esozooplankton are mainly made up of metazoans, which undergo important size changes during their life cycle, resulting in significant variations in metabolic rates. {H}owever, most marine biogeochemical models represent mesozooplankton as protists-like organisms. {H}ere, we study the potential caveats of this simplistic representation by using a chemostat-like zero-dimensional model with four different {N}utrient-{P}hytoplankton-{Z}ooplankton configurations in which the description of mesozooplankton ranges from protist-type organisms to using a size-based formulation including explicit reproduction and ontogenetic growth. {W}e show that the size-based formulation strongly impacts mesozooplankton. {F}irst, it generates a delay of a few months in the response to an increase in food availability. {S}econd, the increase in mesozooplankton biomass displays much larger temporal variations, in the form of successive cohorts, because of the dependency of the ingestion rate to body size. {H}owever, the size-based formulation does not affect smaller plankton or nutrient concentrations. {A} proper assessment of these top-down effects would require implementing our size-resolved approach in a 3-dimensional biogeochemical model. {F}urthermore, the bottom-up effects on higher trophic levels resulting from the significant changes in the temporal dynamics of mesozooplankton could be estimated in an end-to-end model coupling low and high trophic levels.},
