definition –(O) is the element that is essential to life. In the pond it is important because it allow for a larger population of aerobic bacteria, and because aquatic animals depend upon there being enough free oxygen in the water to survive. While oxygen is found in a lot of the molecules in a pond (H20, C02), it needs to be by itself (02) to be [..]
