Key Points
- Lichens are highly sensitive to air pollution, particularly to sulfur dioxide and other pollutants.
- They absorb water and nutrients directly from the atmosphere, which makes them very vulnerable in polluted environments.
- As a result, they are often used as bioindicators of air quality and do not grow well in polluted areas.
- The other organisms:
- Pseudomonas: These bacteria are known for thriving in various environments, including polluted areas, and are often involved in the breakdown of pollutants.
- Algae: Some algae can grow in polluted water bodies, particularly in areas rich in nutrients (like nitrates and phosphates from pollutants), which can lead to algal blooms.
- Gymnosperms: These plants, such as pines and conifers, are less sensitive to air pollution compared to lichens, though some may still be affected.
- Hence, Lichen is the organism that does not grow in polluted areas.
