1. Aquatic Ecosystems Freshwater ecosystems – lakes, rivers, wetlands (marshes & swamps) Marine ecosystems – coastal marshes, estuaries, coral reefs, ocean Abiotic factors that affect life : temperature, light, dissolved oxygen, nutrients

2. Freshwater Ecosystems Categorized as either flowing or standing Wetlands – areas of land covered with fresh water for at least part of the year Important b/c: – Remove pollutants & improve water quality – Control flooding – Home for native & migratory wildlife

3. Marine Ecosystems Estuaries –where fresh water from a river mixes with salt water from the ocean – Home for many organisms, very productive – Animals : fish, dolphins, manatees, otters, crabs, birds – Threats: pollution, human development

4. Marine Ecosystems Coral reefs – areas where coral animals build skeletons & support thousands of organisms (= high biodiversity) – Found in shallow, clear tropical waters – Threats: Coral bleaching – high water temperatures causes coral to die

5. Marine Ecosystems Ocean – Open ocean – phytoplankton perform photosynthesis  eaten by zooplankton  eaten by fish – Deep ocean is dark, cold Supports decomposers, filter feeders – Threats: pollution (runoff, city waste), overfishing, global warming The United Nations Environment Program estimated in 2006 that every square mile of ocean contains 46,000 pieces of floating plastic.
