Solution and Explanation
Step 1: (a) The full form of BOD is Biochemical Oxygen Demand.
Step 2: (b) BOD is the amount of dissolved oxygen needed by aerobic microorganisms to break down organic matter present in a water sample.
Step 2: (b) BOD is the amount of dissolved oxygen needed by aerobic microorganisms to break down organic matter present in a water sample.
- A higher BOD indicates more organic pollution and microbial activity.
- It is an indicator of the level of biodegradable organic matter in the water body.
