Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of them is strongly affected by the other one, which does not seem to be affected at all. Antibiosis is referred to as amensalism interaction.
<u>Antibiosis</u> is the interaction in which one of the species secretes a chemical that kills the other species organism or inhibits its actions by causing severe damage. The organism that releases the toxic substance is called the <u>inhibitor</u>. For the inhibitor species, this relationship is neutral because it does not seem to be beneficiated or affected.
Another classic example of amensalism is those plants that secrete chemicals to damage or kill other plants that live near them. In this way, the secretory plants may live and grow with no competition.
