Well, you have
Mutualism:
One organism hurts another for it's own benefit (e.g. a tick on a deer)
Symbiosis:
Both organisms benefit (e.g. birds eating the insects off a water buffalo)
Commensalism:
One organism benefits while the other has no benefit or harm. (e.g. clown fish hiding in a sea anemone)
There is also the contested Amensalism:
Both organisms are harmed. This one is still in debate amongst zoologists.

Symbiotic Relationships are ecological relationships between different species that are in direct contact with one another. There are three kinds of these relationships: mutualism, commensalism, and parasitism.
Mutualism is a relationship between two different species in which both species benefit. An example is the relationship between nitrogen fixing bacteria and legume plants.
Commensalism is a relationship between two different species in which one species benefits while the other is neither helped nor harmed. An example is cowbirds following cattle, to eat the insects the cattle stir up as they graze.
Parasitism is a relationship between two species in which one species benefits while the other species is harmed. An example is a tick on a dog. For a parasitic species to be successful, it cannot harm the host species so much as to kill the species off.
Disruption of Symbiotic Relationships:
Like the disruption of food webs, removing one species from a biome can harm other species if they had a symbiotic relationship with at species. For example, a population of ticks cannot survive without any host animals on which to feed. Life on earth cannot survive without nitrogen fixing bacteria that provide nitrates for all other plant and animal life.

The larger animal has a smaller animal living on it, it eats dead skin and other small things living on the larger animal there for they both benefit

Like the birds that feed on the debris in Crocadiles teeth. They get good food, and the Crocs have clean teeth.

The friendship among two living organisms where both get benefitted from each other.
