Zooplankton
Heterotrophic protistan or metazoan members of the plankton ecosystem
Zooplankton
Zooplankton are the heterotrophic component of the planktonic community, having to consume other organisms to thrive. The name comes from Ancient Greek ζῷον (zōîon), meaning "animal", and πλαγκτός (planktós), meaning "drifter, wanderer, roamer", and thus, "animal drifter". Plankton are aquatic organisms that are unable to swim effectively against currents. Consequently, they drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton (cyanobacteria and microalgae), which are the plant-like component of the plankton community (the "phyto-" prefix comes from Ancient Greek: φῠτόν, romanized: phutón, lit. 'plant', although taxonomically not plants). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding), often generating biological energy and macromolecules through chlorophyllic carbon fixation using sunlight – in other words, zooplankton cannot manufacture their own...
