Question

Choose the correct option that describes the mutual benefit or harm between two organisms: "One benefits while the other neither benefits nor suffers."

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

Hint:

In symbiotic relationships, commensalism is where one organism benefits while the other is unaffected.

Answer 1

The Correct Option is B

Step 1: Understanding the Question.
The question describes a relationship where one organism benefits while the other remains unaffected, which is characteristic of commensalism.

Step 2: Analyzing the Options.
(A) Parasitism: In parasitism, one organism benefits at the expense of the other, so this is not correct.
(B) Commensalism: Correct — Commensalism is a symbiotic relationship where one organism benefits, and the other is neither helped nor harmed.
(C) Mutualism: This involves both organisms benefiting, which is not the case here.
(D) Predation: In predation, one organism benefits by killing the other, so this is not correct.

Step 3: Conclusion.
The correct answer is (B) Commensalism, as it perfectly fits the description of one organism benefiting while the other remains unaffected.
