  1. Aquatic Ecosystems

  2. Freshwater Ecosystems -Aquifers -Springs -Ponds -Lakes -Creeks/Streams -Rivers -Wetlands Makes up < 3 % of water on earth

  3. Essential for Freshwater Ecosystem • Dissolved Oxygen • Minerals and Nutrients • Species Diversity

  4. Ponds and Lakes Zones: • Littoral • Photic • Benthic Plankton: Zooplankton Phytoplankton ⃪ ⃪ Decomposers

  5. Eutrophication An increase in aquatic plants or alga due to an increase in nutrients.

  6. Large-Scale Eutrophication

  7. Streams, Creeks, and Rivers Stream Order:

  8. Alabama’s Natural Setting • 1,438 miles of navigable channels • 77,000 miles ofrivers and streams • 563,000acres of lakes, ponds, reservoirs • 33.5 trillion gallons of water flow through river systems. • 16 major locks and dams on 6 river systems

  9. Geographic regions of Alabama

  10. Shoal Creek What impact are these dams having on this creek system? Accumulation of water and habitat division.

  11. Human Influence Extensive pollution: -Industrial -Agricultural -pesticides -animal waste -Household waste -septic tanks -Oil spills -Nuclear waste

  12. Why should aquatic ecosystems be a major concern for future scientists? Because the final consumers of water are. . . Humans
