Question

In an interaction where one species is harmed, whereas the other is unaffected is known as:

• A. Commensalism
• B. Amensalism
• C. Parasitism
• D. Mutualism

Hint:

Amensalism = “A” for “Accidental damage” (One is hurt, the other doesn't even notice).

Answer 1

The Correct Option is B

Step 1: Concept
Biological interactions describe relationships between organisms based on their effects.

Step 2: Meaning
Effects are labelled positive (+), negative (-), or neutral (0).

Step 3: Analysis
Commensalism is (+/0). Parasitism is (+/-). Mutualism is (+/+). Amensalism is (-/0): one organism is harmed, the other unaffected.

Step 4: Conclusion
The (-/0) relationship described matches the definition of Amensalism.

Final Answer: (2)
