b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every 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 measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally
