Why does oxygen level in water decrease as a result of dumping biodegradable wastes in a river?
the waste materials take the place occupied by oxygen
Why does the oxygen lvel in water decrease as a result of dumping diodegradable wastes in a river?
In all bodies of water, there live micro-bacteria that need food just like us. These bacteria are not producers like plants; they cannot produce their own food. These bacteria decompose the biodegradable wastes that were dumped. When they do, they need Oxygen in order to break the wastes down into simpler molecules. Therefore, the amount of dissolved Oxygen in the river decreases.
What effect does it has on the hematocrit if the kidneys respond to a decrease in oxygen?
a decrease in oxygen will result with an increase of red blood cell production (more carriers for hemoglobin to compensate for the lower levels of oxygen). The kidneys produce erythropoietin that stimulate RBC production.
