उत्तर
A water body rich in organic matter shows high value of B.O.D.
Explanation:
B.O.D. is the amount of oxygen required by bacteria and other microorganisms to decompose organic matter in water. When a water body contains a large amount of organic matter, the microbial activity increases, consuming more oxygen, which results in a higher B.O.D. value. High B.O.D. indicates severe pollution and oxygen depletion in the water, which can harm aquatic life.
