1. Aquatic Biomes Freshwater Biomes: Wetlands Streams & Rivers Ponds & Lakes Marine Biomes Ocean Coral Reef Estuary

2. Low levels of dissolved salts (less than.1%) Lakes & Ponds

3. Eutrophic Lakes: rich in organic matter and vegetation (water is shallow,warm and murky), some can be considered swamps, bogs, wetlands, etc. “Old” Lakes

4. Oligotrophic Lakes: Low level of organic matter and vegetation (water is deeper, colder and clear) with sandy or rocky bottom. “Young” Lakes

5. Lakes & Ponds: Animals Variety of fish: (bass, pike, panfish, catfish) amphibians, otters, beavers, ducks, geese, wading birds

6. Lakes & Ponds: Insects Variety of microscopic invertebrates: insect larvae

7. Lakes & Ponds: Environmental Concerns Problems: Eutrophication, pollution from industry, alien species, and acid deposition

8. Rivers & Streams Cooler with more dissolved oxygen than lakes and ponds Characterized by moving water along a gradient Gradient determines the strength of the current

9. Faster currents : Trout, salmon, insect larvae, crayfish, salamanders, and little vegetation

10. Slower currents: similar to lakes and ponds, more vegetation

11. Streams & Rivers: Environmental Concerns : similar to lakes and ponds

12. Wetlands Types: Swamps, Bogs, Marshes

13. Wetland Vegetation Grasses, shrubs, rushes & some trees

14. Wetland Animals: Fish, amphibians, waterfowl, reptiles, mammals, muskrats, beavers

15. Holds water which prevents flooding during intense storms Cleans polluted waters Problems: Have been drained or filled in and converted to developments or farmlands
