Zooplankton is a group of small and floating organisms that form most of the heterotrophic animals in oceanic environments. Low feeding rates typically lead to high AE and small, dense pellets, while high feeding rates typically lead to low AE and larger pellets with more organic content. { bidder: 'sovrn', params: { tagid: '346688' }}, They include plants, animals, and other kinds of organisms. { bidder: 'openx', params: { unit: '541042770', delDomain: 'idm-d.openx.net' }}, Through sloppy feeding, excretion, egestion, and leaching of fecal pellets, zooplankton release dissolved organic matter (DOM) which controls DOM cycling and supports the microbial loop.

Jellyfish, and more gelatinous zooplankton in general, which include salps and ctenophores, are very diverse, fragile with no hard parts, difficult to see and monitor, subject to rapid population swings and often live inconveniently far from shore or deep in the ocean. They have a tough exoskeleton made of calcium carbonate and usually have a single red eye in the centre of their transparent head. The term zooplankton comes from two Greek words ‘zoo’ meaning animals and ‘plankton’ meaning drifter. Zooplankton is a categorisation spanning a range of organism sizes including small protozoans and large metazoans.It includes holoplanktonic organisms whose complete life cycle lies within the plankton, as well as meroplanktonic organisms that spend part of their lives in the plankton before graduating to either the nekton or a sessile, benthic existence. Zooplankton The word "plankton" refers to the floating marine organisms that live on the surface of oceans. They catch prey by extending parts of their body through the holes. Plankton are the diverse collection of organisms that live in large bodies of water and are unable to swim against a current. [34], Euglena mutabilis, a photosynthetic flagellate, Zoochlorellae (green) living inside the ciliate Stichotricha secunda, A number of forams are mixotrophic.

Macroscopic zooplankton include pelagic cnidarians, ctenophores, molluscs, arthropods and tunicates, as well as planktonic arrow worms and bristle worms. [5], Through their consumption and processing of phytoplankton and other food sources, zooplankton play a role in aquatic food webs, as a resource for consumers on higher trophic levels (including fish), and as a conduit for packaging the organic material in the biological pump.

(2018) "A paradigm shift in the trophic importance of jellyfish?". [27], Copepods are typically 1 to 2 mm long with a teardrop-shaped bodies. Because of their large size, these gelatinous zooplankton are expected to hold a larger carbon content, making their sinking carcasses a potentially important source of food for benthic organisms.
