Answer:
Add the three data and divided by 3.
Explanation:
Temperature has a great affects on the concentration of dissolved oxygen in a pond because temperature is responsible for the presence of high amount of dissolved oxygen in water. At low temperature such as in winter season, the amount of dissolved oxygen in water is higher while in warm temperature such as in summer season, the concentration of dissolved oxygen is lower. So for measuring the mean dissolved oxygen of the cold pond, you have to add the data and then divided by 3, you will get the average dissolved oxygen of the cold pond.

Nitrogen containing fertilizer are used by farmers to promote crop and plant growth. These fertilizers can runoff into various nearby water bodies. In a process called eutrophication, nitrogen dissolves in a body of water and stimulates the growth of plants and algae. When these plants and algae die, bacterial populations feeding on the dead material increase and consume a lot of oxygen in the water. Which of the following is likely to occur as a result of using nitrogen containing fertilizer?
Answer:
This process will harm marine life due to scarcity and reduction of oxygen levels. This will significantly harm the marine ecosystem as well.
Due to a lack of oxygen and other factors, this procedure will destroy marine life. The marine ecology will also suffer considerably as a result of this.
What is the importance of nitrogen in the environment?Farmers employ fertilizers that contain nitrogen to encourage the growth of their crops and plants. These fertilizers may leak into a number of surrounding bodies of water.
Nitrogen dissolves in a body of water through a process known as eutrophication, which promotes the growth of plants and algae.
Fertilizers give plants the nutrients' potassium, phosphorus, and nitrogen, so they can grow larger, more quickly, and generate more food.
Therefore, nitrogen in particular is a vital ingredient for the growth of every living on Earth.
