A lichen is a two-member symbiotic community consisting of a fungus, which provides structure and some protection, and a photosynthetic algae. There has been a great deal of debate as to whether this relationship is beneficial to the algae, or whether they would grow faster if they were not trapped within the fungal matrix. How would we describe a lichen if it were: a) beneficial to the alga b) provided no benefit to the alga c) slowed the growth of the alga (The fungus definitely benefits from access to fixed carbon.)
