What are active swimmers called? nekton
What are inhabitants of the benthic environment (bottom of a body of water) called? benthos
all organisms 0.2-2 micrometers (bacteria, viruses, archaea, +smallest of phytoplankton) picoplankton
2-20 micrometers; mainly phytoplankton nanoplankton
20-200 micrometers; mostly zooplankton, some phytoplankton microplankton
200-2000 micrometers; mostly zooplankton mesoplankton
2-20 centimeters; starts nekton macroplankton
20-200 centimeters; bigger nekton megaplankton
matter of organic origin, but incapable of reproduction (dead) detritus
passes through a fine filter dissolved
dissolved organic matter; organic material that passes through a fine filter DOM
material that does NOT pass through a fine filter, can be detritus OR inorganic material like sediment particulate
"open ocean", "blue water", water depth >200 m oceanic
beyond low tide out to the edge of the continental shelf (i.e., depth <about 200 m); includes "nearshore" and "estuarine" coastal
"in the water" pelagic
"on or associated with the ocean floor" benthic
