"Determination of Biological oxygen demand (BOD) can help in suggesting the quality of a water body. " Explain

Explanation

### Step-by-Step Solution:

1. **Definition of Biological Oxygen Demand (BOD)**:
- BOD is defined as the amount of dissolved oxygen that aerobic organisms require to decompose organic matter in a water body at a specific temperature over a certain period of time.

2. **Role of Aerobic Organisms**:
- Aerobic organisms, such as bacteria, utilize oxygen to break down organic materials present in the water. This process is essential for the natural recycling of nutrients in aquatic ecosystems.
