Question

Quizplus · Accepted Answer

Biological oxygen demand (BOD) is a measure of the amount of oxygen required by microorganisms to break down organic matter in water. The higher the BOD, the more polluted the water is. Chemical oxygen demand (COD) measures the amount of oxygen required to oxidize all organic and inorganic compounds in water, not just those that can be broken down by microorganisms. Respiration rate, carbon dioxide production, and cell yield are not directly related to measuring the pollution level of water.
