Abstract: The deep-sea benthic community in the Yap Trench is highly food limited,with low biomass but high biodiversity.To investigate the food resources and trophic levels of the benthic community in the Yap Trench,stable carbon and nitrogen isotope ratios of phytoplankton,zooplankton,sedimentary organic matter and megabenthos（include Porifera,Holothuroidea,ophiuroidea,Asteroidea,Actiniaria,Gammaridea）were analyzed.The phytoplankton and zooplankton in the euphotic zone of the Yap Trench is the original ...
