Mutualism: Both Partners Benefit
An example of mutualism is when the Egyptian Plover flies into the mouth of a crocodile and feeds on leftover meat in the crocodile's teeth. This benefits both because it serves as a meal for the Egyptian Plover at the same time cleans the teeth of the crocodile.
Mutualism in the Artic Tundra is lichen that appears like moss but it's actually symbiotic between a fungus and algae. The fungus is fed sugars by the photosynthesis and the algae receives protection from the fungus.
Commensalism: One Species Benefits While the Other is Neither Helped Nor Harmed
The example of commensalism is the remora fish and the shark. The remora fish uses it's dorsal fin to attach to the shark's back. The remora fish eats the scraps the host (shark) leaves behind. The remora fish gains while the shark is neither harmed or helped.
Commensalism in the Artic Tundra is when the artic fox follows the caribou who removes the snow to get at lichens under the soil. The artic fox then hunts the animals that have been dug up by the caribou.
Parasitism: One Organism (parasite) Gains, While the Other (host) Suffers
The example of parasitsim is the deer tick (parasite) attaches to a warmblooded animal (host) and feeds on it's blood. The deer tick (parasite) benefits (gains) while the warmblooded animal/dog (host) suffers a loss of nutrients and can possibly get sick.
Parasitism in the Artic Tundra is the liver tapeworm cysts that are in the moose, caribou and wolves.
