Where is oxygen content in a river or stream likely to be highest a the source?
Oxygen levels are
higher at the source of rivers and streams
, so organisms that require higher levels of oxygen will be found there. Organisms that require lower levels of oxygen will be found nearer the mouth.

Does dissolved oxygen affect pH?
The amount of
dissolved oxygen becomes lower as the water becomes warmer
. … As the hydrogen ions increase, the water becomes more acidic; as the hydroxyl ions increase, the water becomes more basic. pH is measured on a logarithmic scale of 0 – 14: 7 is neutral; below 7 is acidic; above 7 is basic.
Does water increase oxygen level?
2. Drink water. In order to oxygenate and expel carbon dioxide, our lungs need to be hydrated and drinking enough water, therefore,
influences oxygen levels
.
How much oxygen is in our water?
Oxygen concentrations are much higher in air, which is about 21% oxygen, than in water, which is a tiny fraction of
1 percent oxygen
.

Are all lakes connected to rivers yes or no?
12 Answers. Normally, a lake will have a fresh water
