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 Saltwater
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 Phytoplankton are 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

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

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

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

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

27. Angler fish

28. Saltwater
Estuaries
Chesapeake Bay

29. 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

30. 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).

31. 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)
