Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-II, B-III, C-IV, D-I
(A) First — this matches (II) Phytoplankton, trees. Producers make their own food from sunlight, so they form the first trophic level.
(B) Second — this matches (III) Zooplankton, cow. These are herbivores. They feed on the producers, so they are the primary consumers at the second level.
(C) Third — this matches (IV) Birds, fishes. These are shown as carnivores that feed on herbivores. They are the secondary consumers at the third level.
(D) Fourth — this matches (I) Man, lion. These are top carnivores. They are the tertiary consumers at the fourth level, at the top of the chain.
