Answer:
- Brownish- green colour patches on the bark are referred to as lichen.
- Lichen are symbiotic associations between fungi and algae where alga is the autotrophic member ( provides food material ) and fungus is the heterotrophic member( provides water and nutrients by absorption ).
- Lichens do not grow in polluted areas, therefore they are good indicators of air pollution.
