doesn't symbiosis include neutralism and competition as well (as the forms of an interaction btw. organisms)?

Competition no. Neutralism- it depends on the interaction. You need to understand that symbiosis means a close relanshionship that lasts long: "living together"
Competition and predation deffinetly don't fit there.

But predationship can last for a long time, can't it?One side will never completely eat up the second. The number of predators depends on number of their prey (if it falls, the number of predators falls as well), so the relationship regulates itself. Doesn't that work this way?Isn't it a long-therm relationship?

No, because although the relantionship between the 2 species lasts long, the relantionship between any 2 particular organisms when one is the predator species and the other the prey species lasts from a very short time. the relantion is defined between 2 organisms, not 2 species. Otherwise all relationships would be long-term

I think I'm going with this definition. American Heritage Dictionary
Parasite
1. Biology An organism that lives and feeds on or in an organism of a different species and causes harm to its host.

( of a different species ) With emphasis.
