the three types are: parasitism, commensalism, and mutualism.

all three are alike in the fact that they involve two organisms interacting in order to survive.

With parasitism, one organism takes from the other in order to benefit itself. IN this case, one benefits and one suffers. One organism lives inside or on the body of the other (the host), and inflicts damage by doing so. An example would be bacteria or viruses within an organism like a human.

With commensalism, it isn't a matter of who does and does not benefit. One organism eats a portion of food, and the other organism eats what the other one doesn't. It isn't really a sense to teamwork, but neither suffer.

Finally, with mutualism, both organisms benefit. It's essentially teamwork, or cooperation. For example, when a bee pollinates a flower, the bee benefits, but the flower does as well.
