AIIMS 2019 Botany Species Interactions Match the Following Question
Select the correct match (I) (II) (III) (a) + (i) – (P) Amensalism (b) – (ii) – (Q) Commensalism (c) – (iii) 0 (R) Predation (d) + (iv) 0 (S) Competition
a - iv - Q, b - iii - P, c - ii - S, d - i - R
a - i - Q, b - ii - P, c - iii - S, d - iv - R
a - i - Q, b - iii - P, c - ii - S, d - iv - R
a - iv - Q, b - ii - P, c - iii - S, d - i - R
Correct Answer
Detailed Explanation
Option A correctly matches the ecological interactions with their respective symbols: Amensalism (−, 0) is represented by (a) with (iv) and (Q), Commensalism (+, 0) by (b) with (ii) and (P), Predation (+, −) by (d) with (i) and (R), and Competition (−, −) by (c) with (iii) and (S). Other options incorrectly assign the interactions or their symbols, leading to mismatches in the relationships between species. Understanding these interactions is crucial for grasping ecological dynamics, where the symbols represent the effects of one organism on another: positive (+), negative (−), or neutral (0).
