Question:
Study the following and pick up the incorrect statements:
I. In commensalism both partners are benefitted due to each other.
II. In amensalism no partner is benefitted.
III. In parasitism, one partner is benefitted and the other is harmed.
IV. In competition both the partners are benefitted.
Study the following and pick up the incorrect statements:
I. In commensalism both partners are benefitted due to each other.
II. In amensalism no partner is benefitted.
III. In parasitism, one partner is benefitted and the other is harmed.
IV. In competition both the partners are benefitted.
Show Hint
Understanding symbiotic relationships is essential in ecology. Commensalism, amensalism, parasitism, and competition are key concepts.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Statement I is incorrect because in commensalism, only one partner is benefitted while the other is neither benefitted nor harmed.
Statement II is correct as in amensalism, no partner is benefitted; one is harmed while the other is unaffected.
Statement III is correct because in parasitism, one partner (the parasite) benefits at the expense of the other (the host).
Statement IV is incorrect because in competition, both partners are harmed as they compete for the same resources.
Final Answer:
I, IV
Statement II is correct as in amensalism, no partner is benefitted; one is harmed while the other is unaffected.
Statement III is correct because in parasitism, one partner (the parasite) benefits at the expense of the other (the host).
Statement IV is incorrect because in competition, both partners are harmed as they compete for the same resources.
Final Answer:
I, IV
