Biochemical oxygen demand in science definition and examples

Today, we're going to unravel the mysteries of Biochemical Oxygen Demand, or BOD. But before we dive in, let's understand why oxygen is so crucial in aquatic ecosystems. Oxygen is the life force that sustains a myriad of organisms, from tiny microorganisms to large fish. It's involved in various vital processes, such as respiration and decomposition. However, the availability of oxygen isn't infinite. It's a finite resource, and its levels can fluctuate due to natural and human-induced factors. This is where BOD comes into play, as it helps us measure and monitor the oxygen needs and health of aquatic environments.
