  1. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean

  2. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Water Ecosystems that contain water with low salt concentrations – usually less than one percent

  3. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Bodies of flowing fresh water moving in one direction Streams - cooler water temps. Faster moving current, higher oxygen levels, more clear Rivers – warmer water temps. Slower moving currents, lower oxygen levels, less clear

  4. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Bodies of standing fresh water Ponds – smaller bodies of water that often allow sunlight to reach the bottom Lakes – Larger bodies of water that depend upon floating algae to start food chain

  5. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Water Ecosystems that contain water with higher salt concentrations – usually one percent or more Estuary – Area where fresh water of a river meets salt water of an ocean

  6. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Area of shoreline between highest tide line and lowest tide line

  7. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Area of relatively shallow water from low tide line to edge of continental shelf

  8. Aquatic Ecosystems • Fresh Water Ecosystems 1. Streams and Rivers 2. Ponds and Lakes B. Marine Ecosystems 1. Intertidal Zone 2. Neritic Zone 3. Open Ocean Surface zone –region that consists of the top two – three hundred meters from the ocean surface in which light is able to penetrate and support photosynthesis Deep zone - region starting about 1000 meters below surface in which photosynthesis does not occur
