  1. Aquatic Biomes • 1. Freshwater Ecosystem • Rivers and streams • 2. Ocean zones • Marine Ecosystem

  2. Rivers and Streams

  3. How ? • Low lying areas collect runoff water • Streams drain into rivers • Area of drainage is a watershed • PA in Mississippi River watershed • Ohio River Watershed – Wash. County • 15 watersheds in Wash. Co.

  4. River / Stream Ecosystem RIPARIAN BOUNDARY (trees) Pin Oak Elm Sugar Maple Silver Maple ALGAE Green Algae (Spirogyra) Diatoms Gold Algae ANIMALS Birds (Great Blue Heron) Insects (mayfly, stonefly) Mammals (muskrat, raccoon) Fish (smallmouth bass, trout) Mollusks (fingernail clam, orb snail

  5. Algae • Base of food web • Photosynthetic • Oxygen producer

  6. Animals of Stream / River
