Show answer & explanation

Correct answer: D

The oxygen consumed in the oxidation of an organic compound by microorganisms in the aquatic ecosystem is called Biochemical Oxygen Demand (BOD). BOD measures the amount of dissolved oxygen required by aerobic microorganisms to decompose organic matter in water. This distinguishes it from Chemical Oxygen Demand (COD), which involves chemical oxidation, and Dissolved Oxygen (DO), which refers to the oxygen currently present in the water.
