Ai-a, ii-b, iii-c, iv-d

Bi-d, ii-a, iii-c, iv-b ✓ Correct

Ci-b, ii-c, iii-a, iv-d

Di-c, ii-d, iii-a, iv-b

Correct answer: (B) i-d, ii-a, iii-c, iv-b

Explanation

Placing each animal at its feeding rank gives lion at the fourth level, tree at the first, fish at the third and grasshopper at the second.

The tree is a producer, so it occupies the first trophic level.

The grasshopper eats plants, so it sits at the second level as a herbivore.

The fish preys on smaller animals, placing it at the third level.

The lion is a top carnivore, taking the fourth level in this chain.

Energy decreases at each step, so higher trophic levels support fewer individuals.
