Association between Algae and Fungi
The association between algae and fungi is known as Lichen. Lichens are composite organisms consisting of a symbiotic relationship between a fungus and an alga or cyanobacterium. This relationship is mutually beneficial, as both partners contribute to the survival and growth of the lichen.
The algae partner, usually a green alga or a cyanobacterium, provides the lichen with photosynthetic capabilities. It produces organic nutrients through photosynthesis, which are then utilized by the fungus.
The fungus partner provides the lichen with a protective structure and obtains nutrients from the environment. It absorbs moisture and minerals from the surroundings, providing a suitable habitat for the algae or cyanobacterium.
The association between algae and fungi in lichens is essential for their survival and success in various habitats. They can be found in diverse environments, including deserts, forests, tundra, and even on rocks and walls.
Lichens have a significant ecological role as pioneers in colonizing bare or disturbed habitats. They contribute to soil formation, nitrogen fixation, and provide food and shelter for various organisms.
In conclusion, the association between algae and fungi is known as lichen. This symbiotic relationship allows lichens to thrive in various environments and play important ecological roles.
