Question

Match the Pairs

Column- I (Type of Interaction)	Column- II (Mechanism involved)
A) Competition	I) loss of digestive system
B) Prey - predation	II) feeding efficiency of one species is reduced due to interference of other species
C) Mutualism	III) Co-evolution in plants and animals
D) Endoparasitism	IV) Camouflage for concealment

Choose the correct option.

• A. A - IV, B - III, C - I, D - II
• B. A - II, B - IV, C - III, D - I
• C. A - IV, B - III, C - II, D - I
• D. A - II, B - IV, C - I, D - III

Hint:

Link each interaction to its feature: interference, camouflage, co-evolution and loss of digestive system.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Each type of population interaction has a typical feature or adaptation.

Step 2: Match the pairs
Competition: the feeding efficiency of one species is reduced by interference from another (A - II). Prey-predation: prey use camouflage to conceal themselves (B - IV).

Step 3: Match the rest
Mutualism, as in fig and wasp, shows co-evolution of plants and animals (C - III). Endoparasites like tapeworms have lost their digestive system (D - I).

Step 4: Conclusion
The correct combination is A - II, B - IV, C - III, D - I.

Final Answer:
The correct matching is A - II, B - IV, C - III, D - I. \[ \boxed{\text{(B) }\text{A - II, B - IV, C - III, D - I}} \]
