Question:
The interaction where one species is harmed and the other is unaffected is called?
The interaction where one species is harmed and the other is unaffected is called?
Show Hint
Amensalism = "A" for affected (harmed), other is neutral.
Example: Antibiotics killing bacteria without affecting humans directly.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
In ecology, interactions between species can have positive, negative, or neutral effects. These interactions are classified based on how each organism is affected.
Step 1: Understanding types of interactions
• Mutualism: Both species benefit (+, +)
• Commensalism: One benefits, the other is unaffected (+, 0)
• Parasitism: One benefits, the other is harmed (+, --)
• Amensalism: One is harmed, the other is unaffected (0, --)
Step 2: Identifying the correct interaction
The question specifies that one species is harmed while the other is unaffected. This perfectly matches the definition of amensalism. Conclusion:
Therefore, the correct term is amensalism.
