2. Question
1. The Chemical Oxygen Demand (COD) is the total measurement of all chemicals (organics & in-organics) in the water
2. The Biochemical Oxygen Demand (BOD) is a measure of, the amount of oxygen that requires for the bacteria to degrade the organic components present in water.
Which of the above-mentioned statements is/are incorrect?CorrectAns;- c) Both 1 and 2
Explanation;-
• Both the statements are reversed that’s y asnwer is c.
• The Chemical Oxygen Demand or COD is a measurement of the oxygen required to oxidize soluble and particulate organic matter in water.
• The Biochemical Oxygen Demand or Biological Oxygen Demand, is a measurement of the amount of dissolved oxygen (DO) that is used by aerobic microorganisms when decomposing organic matter in water.IncorrectAns;- c) Both 1 and 2
Explanation;-
• Both the statements are reversed that’s y asnwer is c.
• The Chemical Oxygen Demand or COD is a measurement of the oxygen required to oxidize soluble and particulate organic matter in water.
• The Biochemical Oxygen Demand or Biological Oxygen Demand, is a measurement of the amount of dissolved oxygen (DO) that is used by aerobic microorganisms when decomposing organic matter in water. - Question 3 of 5
3. Question
The Algal bloom results in which of the following events?
CorrectAns:- c) Eutrophication
Explanation:-
• The Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae.
• The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events.
• The Algal Bloom are a result of blue-green algae, which are actually bacteria (cyanobacteria).
• Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.
IncorrectAns:- c) Eutrophication

4. Question
The Eutrophication of water bodies leading to killing of fishes is mainly due to non-availability of?
CorrectAns;- d) Oxygen
Explanation;-
• The Eutrophication is the nutrient enrichment of a water body due to natural or accelerated/cultural factors like run-offs from land that causes the growth of plant life(algae) in it.
• These algae uptake the oxygen dissolved in the water making it unavailable and leading to the death of fishes, whose decomposing remains further deplete the water body of dissolved oxygen.
• So, the correct option is ‘ oxygen’.
IncorrectAns;- d) Oxygen

• The Eutrophication is the nutrient enrichment of a water body due to natural or accelerated/cultural factors like run-offs from land that causes the growth of plant life(algae) in it.
• These algae uptake the oxygen dissolved in the water making it unavailable and leading to the death of fishes, whose decomposing remains further deplete the water body of dissolved oxygen.
