Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms require 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 ppm (parts per million). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below. Table 4: Water Quality vs. Fish Population Dissolved Oxygen (ppm) 0 2 4 6 8 1 0 1 2 1 4 1 6 1 8 Number of Fish Observed 0 1 3 1 0 1 2 1 3 1 5 1 0 1 2 1 3 1. What is the question being studied in the experiment presented above? I noticed the lack of dissolved oxygen (ppm) in the water compared to the fish population, which is also zero. This is due to the (ppm), a fish's survival requirement. The fish population observed grows in proportion to the level of (ppm) in the water. I understand that the higher the oxygen levels/availability in the water, the more fish populations the water can support. This correlation is crucial and needs to be further explored. Currently, (ppm) is increasing at a rate of 2. The population suddenly decreased by 5 with a (ppm) of 14 before rising again. Additional circumstances likely contributed to the rapid reduction; more information and research would be
