Answer :
Reasons:
1. Lichens enable algae, which provides carbon dioxide into the atmosphere, which then goes through photosynthesis into oxygen. (we need this to survive.)
2. Food; Lichens provide a big role in several food webs. Which they can be classified as prouducers and provide food for animals because they take care of their own food prouduction.... (animals like, birds, deer, squirrels, and so on.)
3. Medicine; lichens have been used for centuries in medicinal properties. Studies show that lichens help fight off viral infections and certain types of cancers.

Answer:
Lichens are useful as they act as pollutant indicators, like food and medicines.
Explanation:
In lichens, High SO2 concentrations were said to be the main reason for habitat loss, reductions in some species. The most sensitive lichens are shrubby and leafy. Lichens are very sensitive to pollution such as nitrogen because they receive water and nutrients from wet and dry atmospheric deposition. this property makes them a pollutant indicator.
Lichens provide food and also help algae to produce food. they make of their own food production. Bryoria is a genus of lichen used by native Americans.
Lichens in traditional medicine are generally used for treating skin disorders, wound, and digestive issues.
