Detailed explanation-1: -Lichens will also absorb sulfur dioxide present in the dissolved water. Lichens are used widely as an environmental indicator/ bio-indicator. If air is getting badly polluted by the sulfur dioxide then there will be no lichens, only the green algae will be found.
Detailed explanation-2: -Lichens are very sensitive to sulphur dioxide pollution in the air. Since industrialization, many lichen species have become extinct in large areas. Lichens are widely used as environmental indicators or bio-indicators.
Detailed explanation-3: -Thus, lichens and mosses are good indicators of air pollution.
