Understanding Biotic Interactions and Species Effects

This question requires matching different types of biotic interactions (List I) with their specific effects on the participating species (List II).

Matching Biotic Interactions

Here's the breakdown of each interaction:

• Amensalism: Occurs when one species is harmed, while the other is unaffected. This corresponds to Match III.
• Mutualism: A relationship where both species involved benefit. This corresponds to Match IV.
• Commensalism: An interaction where one species benefits, and the other remains unaffected. This corresponds to Match I.
• Parasitism: A relationship where one species (the parasite) benefits at the expense of the other species (the host), which is harmed. This corresponds to Match II.

Correct Match Summary

Based on the definitions, the correct pairings are:

• A. Amensalism relates to III. One species is harmed, other is unaffected.
• B. Mutualism relates to IV. Both are benefitted.
• C. Commensalism relates to I. One species is benefitted, other is unaffected.
• D. Parasitism relates to II. One species is benefitted, other is harmed.

Therefore, the correct sequence is A-III, B-IV, C-I, D-II.

This correct matching corresponds to the option A-III, B-IV, C-I, D-II.
