Option A —
Mutualism
Ecological Relationship: MutualismMutualism is a type of symbiotic interaction where both organisms involved benefit from the relationship. In the case of a lichen, it is not a single organism but a complex partnership between two distinct life forms:
The Phycobiont (Algae or Cyanobacteria): Through photosynthesis, this partner produces food (carbohydrates) for the entire structure.
The Mycobiont (Fungus): The fungus provides the structural framework, protects the algae from harsh environmental conditions, and absorbs water and essential minerals from the substrate.
Why other options are incorrect:
Commensalism: One organism benefits while the other is unaffected. In lichens, both are actively contributing and benefiting.
Amensalism: One organism is harmed or inhibited, while the other remains unaffected.
Parasitism: One organism (the parasite) benefits at the expense of the other (the host), which is harmed.
