Symbiotic RelationshipsThe relationship between algae and lichen is

considered mutualism because the algae provides sugars for the lichen while the lichen provides a solid substrate for the algae to grow on.

Symbiotic RelationshipsThe 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.

Symbiotic RelationshipsThe relationship between tapeworms and

caribou is considered parasitism because the tapeworms get benefited by getting shelter and the caribou is harmed by the tape worms

The relationship between Artic fox and lemmings is also considered parasitism because the artic fox is benefited by eating the lemmings but the lemmings in being harmed by dying.

The tapeworms are the parasite and the artic fox is the host because it is the one being harmed.
