Trophic Levels & Food Chain — NEET Biology
✅ Asked in NEET 2024(NEET 2024) Match List-I with List-II and choose the correct answer: List I A. Tertiary consumer B. Secondary consumer C. Primary consumer D. Primary producer List II I. Grass II. Lion III. Wolf IV. Goat
(NEET 2024) Match List-I with List-II and choose the correct answer: List I A. Tertiary consumer B. Secondary consumer C. Primary consumer D. Primary producer List II I. Grass II. Lion III. Wolf IV. Goat
(NEET 2020) Match the trophic levels with their correct species examples in a grassland ecosystem:- TROPHIC LEVEL A) Fourth trophic level B) Second trophic level C) First trophic level D) Third trophic level SPECIES EXAMPLE (i) Crow (ii) Vulture (iii) Rabbit (iv) Grass
Answer & NCERT explanation
Correct answer: D — A–II, B–III, C–IV, D–I
Following the food chain hierarchy: Primary producer (D) - Grass (I) produces food through photosynthesis. Primary consumer (C) - Goat (IV) eats grass. Secondary consumer (B) - Wolf (III) eats goats. Tertiary consumer (A) - Lion (II) is the apex predator eating wolves. This represents the typical terrestrial food chain: Grass → Goat → Wolf → Lion, as per NCERT ecosystem concepts.

Organisms occupy a place in the natural surroundings or in a community according to their feeding relationship with other organisms. Based on the source of their nutrition or food, organisms occupy a specific place in the food chain that is known as their trophic level. Producers belong to the first trophic level, herbivores (primary consumer) to the second and carnivores (secondary consumer) to the third.
Trophic levels organize organisms by their feeding position: producers (plants) at level 1, primary consumers (herbivores) at level 2, and secondary consumers (carnivores) at level 3. NTA tests this to check if students understand energy flow through ecosystems. The common mistake is confusing trophic levels with organism types—students might wrongly place an omnivore or think a secondary consumer must be at only one level. Remember: trophic level is determined by what an organism eats in that particular food chain, not by the organism's name. An animal eating plants occupies level 2, even if it also eats meat elsewhere.
