Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 1 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from and answer the question below.

Develop a hypothesis that gives a possible explanation for the pattern you see in the amount of dissolved oxygen measured in the water sample related to the number of fish observed in the body of water.
