Answer 2

A. Water quality is indicated by Biological Oxygen Demand.

• Biology Oxygen Demand measures the amount of dissolved oxygen in water required by microbes to derive energy.
• It is indicator of water pollution because the microbes utilize energy from available organic matter. Hence, higher the quantity of organic matter, higher will be the requirement of oxygen to break them down.
• The organic matter is usually fecal contamination, which makes the water unsuitable for drinking.
