text: Ok. 'Biotic' comes from bio=life, living. \n'Action', I'm supposing you know what that is. \n'Inter' is a prefix that indicates, in this case, reciprocal.\nThe reciprocal interactions among living things are extremely diverse. For simplification purposes, ecologists tend to classify them in a few basic categories. For instance, what you're doing by coming to this board and trying to get an answer here is pretty much like _parasitism_. You're taking up our time, that is, it's a loss for us, a gain for you. If, on the other hand, you were willing to give some information in exchange for this one, we could reach a _mutualistic_ interaction. Both participants have a net gain. If somehow we found that we could not live without each other, that would be _obligate mutualism_, although some people call it _symbiosis_. \nIf a rare computer virus chose your computer to spread to the world and destroyed it in the meantime, that would be _parasitoidism_. \n\nI'm sure you can take it from here! Please look for biological examples, these ones won't work.\n\nPD: I'm actually gaining two points, so what type of biotic interaction would that be?
