Aquatic ecosys Flashcards
Biotic factors
Plankton
Nekton
Benthos
Decomposers
Abiotic fsctors
Salinity Water tempt Amount of sunlight Availability of dissolved oxy Nutrients Turbidity
Strong swimmers and consumers
Nekton
Bottom dwelers
Benthos
Freshwater ecosystem have low s levels
Salinity
Standing and moving water
Lentic and lotic
3 zones
Shoreline
Littoral
Limnetic
Benthic
Has shallow sunlit waters
Littoral
High biodiversity in littoral zone bc of
Photosynthetic plants and algae
Most of the photosyn takes place here
Limnetic
Lakes are classified based on
Nutrient levels
Biodiversity
Lakes low in nutrients
Oligotrophic
Greater concentration of nutrients
Eutrophic
Population of P and A are very ___ in oligotrophic
Planktons and algaes, low
How are rivers formed

Aquatic zone biggest limiting factor
Sunlight
Nutrients
Hightide mark to continental shelf
Coastal zone
Bodies of water where there is brackish water
Estuaries
Coastal wetland dominated by tides, full of herbs grasses and shrubs
Salt marsh
Wetlands with plants that have long and narrow leaves
Sea grass bed
Wetlands with trees that have survived high salt, low oxy water
Mangrove swamps
Wetland benefits
Biodiversity
Protect
Clean
What causes intertidal zone
Gravity

Rocky shores
Gentle wave actions or sheltered
Sandy shores
Marine desert
Open oceans
Water charac in open ocean
Photic
Aphotic
Benthic
Source of energy in benthic zone
Dead matter or marine snow
To produce and emit light
