Lab 9 Freshwater Ecosystems Lab

Part A -
1) My freshwater ecosystem a stream behind my house in Rimrock AZ.

3) Temperature - The temperature of the water is 18 degrees Celsius. 

 4) Turbidity - The Turbidity is 0 JTU

8)Ph - The PH of the water is 8

5)Dissolved Oxygen - The dissolved oxygen is an 8.

7)Nitrate - the nitrate level is 5.

11) test factor:                           result:                                 Rank:

      Dissolved Oxygen                8   84%                               3 (good)

      Coliform Bacteria               Negative                             3 (good)

      pH                                         8                                          3 (good)

      Temperature Change         0 degrees                            4 (excellent) 

      nitrate                                  5 ppm                                 2 (fair)

      phosphate                            2 ppm                                 3 (good)

      turbidity                              0 JTU                                 4 (excellent)

B) "dissolved oxygen in water is held more at colder temperatures than it is in warmer temperature water.  The nitrate in water is needed by all aquatic plants and animals to build protein. pH is how acidic the water is its best to have a neutral level. phosphate is needed by plants and animals for growth. temperature is extremely important it determines the level of dissolved oxygen, rate of photosynthesis and the sensitivity of organisms to toxic wastes, parasites and disease."

Part B - 

1) "I am doing my summary on The Red Sea - Dead Sea By Kristiana Donnelly.

The article discusses the Dead Sea which is located by Jordan, Israel, and Palestinian National Authority. It talks about Israel in 1993 proposing to desalinate the water in the Dead Sea to create 1 billion cubic meters of water. It did not happen because it would have costed 4.2 billion dollars and the national bank said that they would not help."

2) I thought this was awesome I had no idea you could desalinate water. Except through evaporation. If we could do this everywhere we would not have to worry about water shortage. Although I do not know the impact it would create on sea life and even level. Its too bad  that it cost to much for them the countries to desalinate the water. Not only would it create a lot of water for nations that need it but it could show us possible circumstances that would happen if we did it in other oceans.
