2. Lichens are good bio-indicators for air pollution.
Which of the above statements are incorrect?
Both 1 and 2
Incorrect AnswerNeither 1 nor 2
Correct AnswerExplanation:
A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship
Lichens can be used as air pollution indicators, especially of the concentration of sulphur dioxide in the atmosphere. Lichens are plants that grow in exposed places such as rocks or tree bark. They need to be very good at absorbing water and nutrients to grow there.
