1. com·men·sal·ism (kə-mĕn'sə-lĭz'əm)
a symbiotic relationship between two organisms of different species in which one derives some benefit while the other is unaffected.
2. par·a·sit·ism (păr'ə-sĭ-tĭz'əm, -sī-)
a symbiotic relationship in which one species, the parasite, benefits at the expense of the other, the host.
3. mu·tu·al·ism (myū'chū-ə-lĭz'əm)
a symbiotic relationship in which both species benefit.
4. com·pe·ti·tion (kŏm'pĭ-tĭsh'ən)
the simultaneous demand by two or more organisms for limited environmental resources.
5. predation
form of food getting in which one animal, the predator, eats an animal of another species, the prey, immediately after killing it or, in some cases, while it is still alive.
6. protocooperation
it is where two species interact with each other beneficially; they have no need to interact with each other they interact purely for the gain that they receive from doing this. It is not at all necessary for protocooperation to occur; growth and survival is possible in the absence of the interaction. The interaction that occurs can be between different animal kingdoms.

Add predation to the list above.

I'm not sure if this is what you are looking for but I have five:
Commensalism
Parasitism
Mutualism
Competition
Reproduction
