considered mutualism because the algae provides
sugars for the lichen while the lichen provides a solid
substrate for the algae to grow on.
Symbiotic Relationships
 The relationship between arctic fox and polar bear is
considered commensalism because the arctic fox gets
benefited by eating what’s left of the polar bear meal,
and the polar bear isn't affected or harmed.
