2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.

  • biology -

    First, are you talking about live fish?

    If so, the level of oxygen needs to be great enough for the needs of these fish. Also the sizes of the fish would effect the amount of oxygen needed.
