Water would become polluted due to biodegradable waste content in it. During the decomposition of the waste, the oxygen naturally dissolved in water would be:Question 14Select one:A.All of the optionsB.Used up by the decomposing wasteC.In high demand in the BOD- Oxygen Biological DemandD.starved to the aquatic lifeE.Depleted

The correct answer is A. All of the options.

Here's why:

B. Used up by the decomposing waste: As biodegradable waste decomposes, it uses up the oxygen in the water. This is because the bacteria and other microorganisms that break down the waste require oxygen to survive and function.

C. In high demand in the BOD- Oxygen Biological Demand: BOD, or Biological Oxygen Demand, is a measure of the amount of oxygen that bacteria and other microorganisms need to decompose organic material in water. When there's a lot of biodegradable waste in the water, the BOD is high, meaning there's a high demand for oxygen.

D. Starved to the aquatic life: When the oxygen in the water is used up by decomposing waste, there's less available for the fish and other aquatic life. This can lead to a condition called hypoxia, where there's not enough oxygen in the water to support life.

E. Depleted: This is another way of saying that the oxygen is used up. When there's a lot of biodegradable waste in the water, the oxygen can be depleted to the point where the water becomes anoxic, or completely without oxygen.
