Areas where land is periodically underwater.
Organisms that cannot swim against currents, they are drifters. The majority are microscopic.
Fresh Water Ecosystem
How they form:
Naturally, where groundwater reaches Earth’s surface
Unnaturally – damming or rivers by humans or beavers
Life in the littoral zone
Life in the benthic zone
Fish adapted to cooler water
Dominated by woody plants (trees and shrubs)
-Occur on flat, poorly drained land often near streams
Species of trees depends on salinity
Birds such as wood ducks
Ideal habitat for amphibians (frogs, salamanders, etc)
Reptiles (ex. Alligator)
-Contain non woody plants (cattails)
-Tend to have low, flat lands and little water movement
-Benthic zones are nutrient rich and contain plants, decomposers, and scavengers
-Wide variety of water birds (ducks, herons, etc)
-Salinity varies(some slightly saline, some as salty as the ocean)
At it’s headwaters river is cold and full of oxygen
-As it flows down mountain it becomes warmer, wider, and slower, containing more vegetation and less oxygen
As it flows nutrients are added to river from sediment and runoff
Plants set roots in river’s rich sediment
Fish such as catfish and carp
