Parameters Dominant Vegetation Dominant Animal life Distribution Lakes and ponds Bodies of (freshwater) standing water (lentic) Low concentration of dissolved solids; seasonal vertical stratification of water Rooted and floating plants, phytoplankton Zooplankton, fish, insect larvae, turtles, ducks, geese, swans, wading birds (heron) Physical depressions in the landscape where precipitation and groundwater accumulate

Parameters Streams and Rivers (freshwater) Dominant Vegetation Flowing water Attached algae, (lotic); low level rooted plants of dissolved soilds; high level of dissolved oxygen; often turbid from runoff Dominant Animal life Distribution Insect larvae, fish, amphibians, otters, raccoons, wading birds, ducks, geese Landscapes where precipitation and groundwater flow by gravity toward oceans or lakes

Parameters Dominant Vegetation Dominant Animal life Distribution Inland Wetlands Standing (Freshwater) waters, at times seasonally dry; thick organic sediments; high nutrients Marshes (grasses, reeds); cattail swamps (water-tolerant trees); bogs (sphagnum moss, shrubs) Amphibians, snakes, numerous invertebrates, wading birds, alligators turtles Shallow depressions, poorly drained, often occupied sites of lakes and ponds that have filled in
Estuaries • https: //www. youtube. com/watch? v=XLum. SN 4 G 5 P 4 Aquatic Systems Major Enviro. Parameters Dominant Vegetation Dominant Animal life Distribution Estuaries (mixed) Phytoplankton, rooted grasses (salt-marsh grasses), mangrove swamps in tropics with salt tolerant trees, shurbs. Zooplankton, rich shellfish, worms, crustaceans, fish, wading birds, sandpipers, ducks, geese Coastal regions where rivers meet the oceans; may form bays behind sandy barrier islands. Variable salinity, tides create two way currents; often rich in nutrients, turbid
Coastal Oceans • https: //www. youtube. com/watch? v=e. Iul 2 Obv. KV 8 Aquatic Systems Major Enviro. Parameters Dominant Vegetation Dominant Animal life Distribution Coastal Oceans (saltwater) Phytoplankton, large benthic algae, turtle grass, symbiotic algae in corals Zooplankton; rich bottom fauna of worms, shellfish, crustaceans; coral colonies, jellyfish, turtles, gulls, sea lions, seals, dolphins, penguins, whales (think Nemo) From coastline, outward over continental shelf, coral reefs abundant in tropics Tidal currents promote mixing; nutrients high
