Lichens are capable of growing on bare rocks, making them the first organisms to colonize such areas. They can secrete acids that break down the rock,
gradually creating soil, which then supports further plant growth. Lichens are considered pioneer species that help initiate the process of primary ecological succession.
Information Booster:
• Lichens are made up of a fungus and alga or cyanobacterium in a symbiotic relationship.
• Ecological succession can be divided into primary and secondary succession, where primary involves barren areas and secondary occurs in areas with existing soil.
• They are known for their ability to thrive in extreme environments with minimal nutrients.
• Lichens are used as bioindicators to monitor air quality and pollution levels.
