Terms which explicitly indicate the quality of benefit or harm in terms of fitness experienced by participants in an interaction are listed in the chart. There are six possible combinations, ranging from mutually beneficial through neutral to mutually harmful interactions. The level of benefit or harm is continuous and not discrete, so a particular interaction may be have a range from trivially harmful through to deadly, for example. It is important to note that these interactions are not always static. In many cases, two species will interact differently under different conditions. This is particularly true in, but not limited to, cases where species have multiple, drastically different life stages.

Famous quotes containing the words interactions and/or effect:
“The exercise of power is determined by thousands of interactions between the world of the powerful and that of the powerless, all the more so because these worlds are never divided by a sharp line: everyone has a small part of himself in both.”
—Václav Havel (b. 1936)
“The sensation of seeing extremely fine women, with superb forms, perfectly unconscious of undress, and yet evidently aware of their beauty and dignity, is worth a week’s seasickness to experience.... To me the effect [of a Siva dance] was that of a dozen Rembrandts intensified into the most glowing beauty of life and motion.”
—Henry Brooks Adams (1838–1918)
