Removal or degradation of environmental pollutants or toxic materials by living organisms is called__________?
Correct answer: D. Bioremediation
- A. Integrated disease management
- B. Hydroponic culture technique
- C. Pasteurization
- D. Bioremediation
Explanation
Bioremediation uses living organisms, especially microorganisms or plants, to break down, remove, or detoxify environmental pollutants. Hydroponics is a method of growing plants without soil, so it is the likely alternative for students who focus on plants rather than pollutant removal. The other options concern disease management or food treatment.
