2. 1.What are the aquatic ecosystems on Earth? 2. Freshwater 3. low concentrations of salt 3. 2.5% of water on Earth 3. Rivers and Streams 4. travel in one direction, ending at the mouth 4. the slope of the landscape determines this

3. 4. can carry sediment 5. material that is deposited by water, wind or glaciers 3. Lakes and Ponds 4. inland body of standing water 4. 3 zones – based on amount of sunlight

4. 5. littoral zone 6. shallow, sunlight hits the bottom 6. plants and algae, frogs, turtles, worms, fish and crustaceans 5. limnetic zone 6. open water that gets a lot of light 6. plankton and fish

5. 5. profundal zone 6. deepest area 6. cold and lower in oxygen

7. 2. Transitional Aquatic Ecosystems 3. Wetlands 4. marshes, swamps and bogs 4. reptiles, amphibians and birds 4. cattails, water lilies, cypress and willows

9. 3. estuary 4. a place where freshwater streams/ rivers meet the ocean 4. most diverse ecosystem 4. many different types of plants and animals live there

11. 2. Marine Ecosystem 3. intertidal 4. where the ocean meets land 3. open ocean 4. 3 zones 4. as it gets deeper the less light there is 3. coastal ocean/coral reefs 4. corals are not hard, but actual animals
