Decrease in $BOD$ of pond water - Increase in global temperature

Vedclass · Answer

(D) The correct answer is $D$. The pair 'Decrease in $BOD$ of pond water - Increase in global temperature' is incorrectly matched. $BOD$ stands for Biochemical Oxygen Demand. When the amount of organic matter in water increases,the $BOD$ increases because microorganisms consume more oxygen to decompose the organic waste. An increase in global temperature (global warming) does not cause a decrease in $BOD$; rather,it can affect the dissolved oxygen levels in water,but it is not the direct cause of a decrease in $BOD$.
