What is the opposite of symbiosis?

If we're considering the term "symbiosis" in the biological sense, where two different species live together in a mutually beneficial relationship, the opposite would be a situation where two or more species interact in a way that is harmful to at least one of them. This could be described as parasitism, where one species benefits at the expense of another, or competition, where both species are negatively impacted by their interaction. However, if we're looking for a broader term that encompasses any non-mutually beneficial relationship, it might be simpler to say that the opposite of symbiosis is simply any kind of interaction that is not mutually beneficial or harmonious. Do you agree with this assessment, or do you have a different perspective on what the opposite of symbiosis might be?
