Marine food webs depend on the photosynthetic production of minute, mostly unicellular algae (phytoplankton) which are autotroph and represent the bulk of primary producers in the sea. Heterotrophic zooplankton feeds - as primary and secondary consumers - on the phytoplankton directly or indirectly. They themselves provide food for larger animals. The exudates, feces and carcasses of zooplankton together with other particulate organic matter form 'marine snow' that serves as food for other organisms. As in all coenoses parasitism also occurs among planktonic organisms. The Microoniscium larval stage of certain isopods (e.g. of the Bopyridae = Epicaridea) attaches as an ectoparasite to copepods and feeds on the hemolymph of its host.
