In terms of biotic interactions, what does amensalism specifically refer to?

Amensalism specifically refers to a relationship between two organisms where one is unaffected and the other is harmed. In this interaction, one species may produce substances that are detrimental to another species without necessarily benefiting itself. A classic example of amensalism is when a large tree shades smaller plants, limiting their access to sunlight and thus harming them, while the tree itself remains unaffected by the presence of these smaller plants. This relationship highlights the complexities of ecological interactions, showing that not all biological relationships are mutually beneficial or detrimental.
