Lichens are the composite or dual organisms representing a symbiotic association between a fungus and alga. The fungal partner is called mycobiont whereas algal partner is called phycobiont. Algae prepares food for fungi and fungi provides shelter and absorbs mineral nutrient and water for its partner. Lichens grow on barren rocks, cooled volcanic lava and icy tundra soils. They can tolerate extreme dessication and are pioneers of rock vegetation. The are very sensitive to air pollution and do not grow in polluted area. They are very good pollution indicators Certain lichens or source of food for grazing animals.

Formation of Lichens

- Lichens are formed by a symbiotic association between a fungus (mycobiont) and an alga (phycobiont).
- The most common partnership in lichens is between blue-green algae (cyanobacteria) and club fungi.

Symbiotic Relationship

- The algal partner (cyanobacteria) photosynthesizes and produces food for the fungal partner.
- The fungal partner provides shelter and absorbs mineral nutrients and water for the algal partner.

Adaptation and Habitat

- Lichens can grow on barren rocks, cooled volcanic lava, and icy tundra soils.
- They can tolerate extreme desiccation and are pioneers of rock vegetation.

Sensitivity to Pollution

- Lichens are very sensitive to air pollution and do not grow in polluted areas.
- They are used as pollution indicators in environmental studies.

Food Source and Grazing Animals

- Some lichens serve as a food source for grazing animals.
- They play a role in the ecosystem by providing nutrition for certain animals.

In conclusion, most lichens are formed by a symbiotic relationship between blue-green algae and club fungi. This partnership allows lichens to thrive in harsh environments, while also serving as indicators of environmental health and providing food for grazing animals.
