Question:
In which ecological interaction is one species harmed while the other is unaffected?
In which ecological interaction is one species harmed while the other is unaffected?
Show Hint
Remember the interaction symbols: Mutualism (+/+), Commensalism (+/0), Parasitism (+/−), and Amensalism (−/0).

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Ecological interactions describe the relationships between organisms living in the same environment. Different types of interactions affect the species involved in different ways.
• Mutualism: Both species benefit.
• Parasitism: One benefits while the other is harmed.
• Commensalism: One benefits while the other is unaffected.
• Amensalism: One species is harmed while the other remains unaffected.
Step 1: Identify the definition given in the question.
The interaction described is where one organism suffers harm while the other organism does not experience any benefit or harm.
Step 2: Match with the correct ecological term.
This interaction corresponds to amensalism.
Step 3: Example of amensalism.
A classic example is the production of antibiotics by certain fungi that inhibit bacterial growth without affecting the fungus itself. \[ \boxed{\text{Amensalism}} \]
