Term
Lotic
Definition
Flowing-water
Term
Lentic
Definition
Nonflowing-water
Term
Littoral Zone
Definition
Shallow-water zone, light hits bottom, plant root growth
Term
Limnetic zone
Definition
Open water, extends to depth of light penetration
Term
Nekton
Definition
free swimming organisms, like fish
Term
Profundal zone
Definition
past the depth of effective water penetration, respiration balances photosynthesis
Term
Benthic
Definition
bottom zone, common to the littoral and profundal zones, most decomposition takes place here
Term
Periphyton/aufwuchs
Definition
associated with benthic community, mostly algae and diatoms dwelling on plants
Term
Eutrophy
Definition
high in nutrients
Term
Oligotrophy
Definition
low in nutrients
Term
Dystrophic
Definition
"ill -nourished", associated with peat and bogs, highly acidic
Term
Riffles
Definition
fast flowing, site of primary production
Term
pools
Definition
slow flowing, site of primary decomposition
Term
Shredders
Definition
shred leaves and shit
Term
Filtering/gathering collectors
Definition
pick up fine particulate organic matter (FPOM)
Term
Grazers
Definition
feed on algae, and shit
Term
Gougers
Definition
burrow into trees and whatnot
Term
Estuary
Definition
Where freshwater and saltwater meet
Term
Anadromous fish

Benthic
Definition
bottom zone
Term
Neritic province
Definition
part of the pelagic zone that overlies the continental shelf
Term
Oceanic province
Definition
part of the pelagic zone that DOESN'T overly the continental shelf
Term
Epipelagic/photic zone

below the mesopelagic, near complete darkness
Term
Abyssopelagic
Definition
extends 4,000 meters to sea bottom
Term
Hadalpelagic
Definition
found in deep sea trenches
Term
Nanoplankton
Definition
smaller than diatoms, make up largest biomass in temperate and tropical waters
Term
Microbial loop
Definition
small things eating each other and their by-products in the ocean
Term
Fringing reefs
Definition
grow seaward from the land
Term
Barrier reefs
