Freshwater and saltwater biomes

1. Freshwater Biomes -Salt concentration < 1% -Ponds and Lakes -Streams and Rivers -Wetlands

2. Ponds and Lakes -Lentic Systems= non-flowing water -Range in size -Limited species diversity -”Zones” determined by depth

3. Ponds and Lakes Littoral Zone Limnetic Zone Profundal Zone

4. Streams and Rivers -Lotic Systems = flowing water -Moves in one direction -Characteristics change from source to mouth -High species diversity

5. Wetlands -Areas of standing water that support aquatic life -Highest species diversity -May be dry part of year

6. Marine Biomes -Saltwater ecosystems -Oceans -Coral Reefs -Estuaries

7. Oceans -Largest Ecosystem -Great species diversity -”Zones” determined by depth

8. Oceans Intertidal Zone Pelagic Zone Abyssal Zone Benthic Zone

9. Coral Reefs -Found in warm, shallow water -Barriers along continents -Dominant organism is coral

10. Estuaries -Where ocean water meets fresh water -Brackish water -Unique ecosystem
