Select the correct food-chain from producer to top predator among the given organisms. (i) Frog (ii) Eagle (iii) Grasshopper (iv) Snake (v) Grass

Introduction / Context:
This is another trophic-level ordering problem, identical in structure to a standard meadow chain.

Given Data / Assumptions:

• (v) Grass: producer.
• (iii) Grasshopper: primary consumer.
• (i) Frog: secondary consumer.
• (iv) Snake: tertiary consumer.
• (ii) Eagle: apex predator.

Concept / Approach:
Strictly increase trophic level each step.

Step-by-Step Solution:
1) v → 2) iii → 3) i → 4) iv → 5) ii.

Verification / Alternative check:
Cross-check with ecological roles for each organism.

Why Other Options Are Wrong:
Options that place consumers before producers or invert predator–prey relationships fail trophic logic.

Common Pitfalls:
Confusing a food web with a single linear chain.

Final Answer:
(v), (iii), (i), (iv), (ii)
