Answer
The symbiotic association between fungi and algae is called lichen. In this unique partnership, the fungus provides protection, moisture retention, and structural support, while the algae or cyanobacteria (photobiont) perform photosynthesis to produce food for both organisms. This mutualistic relationship allows lichens to thrive in extreme environments where neither organism could survive independently, such as bare rocks, tree bark, and arctic tundra. Lichens serve as important ecological indicators of air quality and play crucial roles in soil formation and nutrient cycling in ecosystems.
