Which of the following traits is characteristic of "amensalism"?

Amensalism is a type of interaction between two species where one species is harmed while the other remains unaffected. This relationship highlights a specific dynamic in ecological interactions, wherein one organism can negatively impact another without any reciprocal effect. A common example of amensalism can be seen in the case of larger animals trampling smaller vegetation; the plants (the affected species) suffer damage or death, while the large animals (the unaffected species) experience no change as a result of their presence.

The other options do not accurately define amensalism. While option A describes mutualism, where both species benefit from the interaction, option C inaccurately suggests that no interaction occurs at all. Option D indicates that both species are negatively impacted, which aligns more with competition rather than amensalism. Understanding the nuances of these interactions helps clarify the specific nature and implications of amensalism in ecological contexts.
