Question

Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST

Your answer:

Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.


Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.
