There are three, though individual cases are somewhat in dispute.
1. Parasitism, by far the most common. One organism associates with another because it's using it as a food source.
2. Commensalism. One organism associates with another because it obtains an advantage, but doesn't directly feed on the other.
3. Mutualism. Two (or possibly more) organisms form an alliance because they can live better together than either could alone.
In practice, it can be very difficult to identify the degree of a contribution to a symbiosis, and for this reason, many examples of "commensalism" and "mutualism" are subject to challenge.
Incidentally, the term "symbiosis" is frequently heard from non-biologists who misunderstand it to mean "synergy."
