Answer 2

Answer:

Lichens are the organism which can monitor air pollution.

Explanation:

Organisms which can provide the qualitative measurement of the environment are called bio indicators. These organisms provide the information about the changes in environmental conditions by showing the changes in their physiology, growth and behavior.

The availability of lichens in a certain environment ensure the quality of the air in that locality. Lichens are an example of symbiotic relation between green algae and fungi. They can be seen usually on rocks, trees, and other structures in forests. Lichens are able to respond to the environmental changes in forest in terms of air quality, climates. Poor growth or death of lichens may indicate the presence of sulfur based pollutants in the air.
