Correct Answer: Lichen


Solution : The correct answer is Lichen .

Lichen is a symbiotic association between algae and fungi in which algae produce food, and fungi provide shelter. They are pioneer species in the terrestrial ecosystem and act as a biological indicator for pollution. They show high sensitivity to sulphur dioxide, and cannot survive in places with pollution. Locations having lichen growth indicate that air condition is good.
