Match List $I$ with List $II$ :
| List $I$ (Interaction) | List $II$ (Species $A$ and $B$) |
| $A$. Mutualism | $I$. $+(A), 0(B)$ |
| $B$. Commensalism | $II$. $-(A), 0(B)$ |
| $C$. Amensalism | $III$. $+(A),-(B)$ |
| $D$. Parasitism | $IV$. $+(A),+(B)$ |
Choose the correct answer from the options given below:
A
A-III, B-I, C-IV, D-II
B
A-IV, B-II, C-I, D-III
C
A-IV, B-I, C-II, D-III
D
A-IV, B-III, C-I, D-II
(NEET-2023)
Solution
$(+,+)$ Mutualism : In this interaction, both the interacting species are benefitted.
$(+, 0)$ Commensalism : Only one species is benefitted and the other species remains unharmed.
$(-, 0)$ Amensalism : Neither species is benefitted. One remains unharmed and the other is harmed.
$(+,-)$ Parasitism : One species is benefitted and other is negatively effected.
