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 desiccation 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.

Lichens are the composite or dual organisms representing a symbiotic ...
Explanation:
Lichen Composition:
- Lichens are composite or dual organisms representing a symbiotic association between a fungus and an alga.
- The fungal partner in lichens is called mycobiont, while the algal partner is called phycobiont.
Roles of Mycobiont and Phycobiont:
- The algae in lichens prepare food through photosynthesis, providing nutrients to the fungus.
- The fungus provides shelter and absorbs mineral nutrients and water for its algal partner.
- This mutualistic relationship allows lichens to survive in harsh environments such as barren rocks, volcanic lava, and icy tundra soils.
Adaptations and Environmental Indicators:
- Lichens can tolerate extreme desiccation and are pioneers of vegetation on rocks.
- They are very sensitive to air pollution and do not grow in polluted areas, making them excellent indicators of environmental pollution levels.
Role in Ecosystem:
- Some lichen species serve as a source of food for grazing animals, contributing to the ecosystem's food chain.
Conclusion:
In conclusion, mycobiont and phycobiont are found in lichens, where the fungus and alga work together in a symbiotic relationship to survive in harsh environments, indicate environmental pollution levels, and contribute to the ecosystem's food chain.
