Question

A lichen is a combination of fungus and algae that lives on the sides of trees, rocks, and other materials. The fungus provides the algae with water and minerals and the algae uses the water and minerals to make food for both organisms. What ecological relationship does the lichen represent and why?

Answer 1

Answer:

Symbiosis (mutualism)

Explanation:

The lichens are mutually beneficial relationships between algae (and/or cyanobacteria) and fungus. In these symbiotic relationships, the fungus is dominant and it gives to the lichen its most important morphological features.
