Question

Match List I with List II:

List I (Interaction)	List II (Species A, Species B)
A. Amensalism	I. +, −
B. Predation	II. −, −
C. Commensalism	III. +, 0
D. Competition	IV. −, 0

Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
• (A) - (IV), (B) - (III), (C) - (I), (D) - (II)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)

Hint:

Interaction types are defined by how species benefit (+), are harmed (-), or are unaffected (0).

Answer 1

The Correct Option is D

• Amensalism (A): One species is negatively affected, while the other remains unaffected, represented by IV. -, 0.
• Predation (B): One species benefits (predator) and the other is harmed (prey), represented by I. +, -.
• Commensalism (C): One species benefits, and the other is neither helped nor harmed, represented by III. +, 0.
• Competition (D): Both species are negatively affected due to limited resources, represented by II. -, -.
