  1. Water Biomes

  2. Limiting factors limit populations in any ecosystem

  3. What are limiting factors in water biomes (abiotic)? Salinity- Amount of Salt Sunlight Amount of Dissolved Oxygen

  4. 3 Types of Water Biomes • Freshwater • Rivers and Streams • Lakes and Ponds • Saltwater • Ocean • Seashores (tidal areas) • Estuaries- area where fresh water mixes with salt water

  5. Freshwater Biomes Freshwater contains little or no salt, so it has a LOW salinity. Flowing freshwater = rivers and streams Still Freshwater = lakes and ponds

  6. Flowing Freshwater • Streams • The faster a stream flows the greater the amount of dissolved oxygen in it. Faster water flows = oxygen

  7. Flowing Freshwater • Streams • The fish that live in streams are adapted to fast moving water

  8. Flowing Freshwater • Rivers • Water moves slower in a river and debris settles on the bottom. • Because of this, rivers tend to have more nutrients and less dissolved oxygen. nutrients and oxygen

  9. Flowing Freshwater • Rivers

  10. Freshwater • Ponds • Small, shallow bodies of water • Sunlight penetrates all the way to the bottom • Most completely filled with plant material • Very high amount of nutrients

  11. Freshwater • Ponds

  12. Freshwater • Lakes • Larger and deeper than ponds • Plant growth is limited to the shoreline • Sunlight does NOT penetrate to the bottom= no plants after a certain depth!

  13. Freshwater • Lakes

  14. Marine Biome Plankton are microscopic algae, plants, and other organisms that float on the surface of water biomes. Phytoplankton need sunlight to survive.

  15. Where does energy enter this ecosystem? Circle the herbivores Are there any omnivores?

  16. Water Biomes Phytoplanktonare important producers in water biomes. They are the first step in many aquatic food chains

  17. Saltwater Biomes About 95% of the water on Earth has a high concentration of salt. (High salinity) LARGEST BIOME!

  18. Saltwater • Seashores • Tides have a huge influence on life here • INTERTIDAL ZONE- portion of the shoreline that is covered with water at high tide and exposed to the air at low tide.

  19. Intertidal Zone • Can be sandy or rocky • Small fish, clams, crabs, other mussels are trapped in the TIDAL POOLS during low tide

  20. Intertidal Zone

  21. Saltwater • Oceans • Can be divided into 2 main life zones Photic zone & Aphotic zone

  22. 1. Photic Zone- above 200m • Sunlight penetrates • Plant life and animal life is abundant

  23. 2. Aphotic Zone- below 200m • Sunlight DOES NOT penetrate • There are no plants • Animal life is highly adapted for no light

  24. Aphotic Zone- below 200m • Many of the organisms of the deep ocean have a special adaptation known as bioluminescence

  25. Angler fish

  26. Saltwater • Estuaries • Chesapeake Bay

  27. Estuaries • Estuaries (Wetlands) • Area where a river meets an ocean • Mix of salt and freshwater • Located near coastlines, border land • Extremely fertile • Nutrient levels are higher than both salt and freshwater

  28. Creating a cover page Your job is to design 1 cover page that incorporates the 6 major biomes creatively. You may do this anyway you wish (creatively or by just dividing up your paper into 6 sections).

  29. Here are your requirements • All six biomes must be represented on you cover page using illustrations. (40 points) 2. Each biome represented must have 2 of the key words from that Versals labeled in the illustration. (go back and check the key words) (30 points)  3. Each Biome represented on the cover page must be titled with it's proper name (ex: Desert, Grassland, etc.) (10 points) 4. The Cover sheet must be colored neatly. (15 points)  5. YOUR NAME and PERIOD must be visible (5 points)
