Oxygen-depleted (hypoxia) zones of the oceans, such as the one at the mouth of the Mississippi River, are most likely caused by

• large numbers of fish that are using up all the oxygen in the water

• a reduction in the plant life in rivers that empty into the ocean near the dead zone

• excessive fertilizers carried into the ocean, which cause algal blooms that lower the oxygen levels

• thermal pollution in the ocean

What is the difference between DO and BOD?

• DO is how much O₂ is present in the water whereas BOD is the number of organisms present.

• DO is how much O₂ is present in the water whereas BOD is the measure of oxygen used by organism for metabolic processes.

• As BOD decreases dissolved O₂ present in the water decreases.

• As BOD decreases dissolved CO₂ present in the water increases.
