Tertiary Consumer b . Primary Carnivores x . Fourth 3 . Rodents i i i . Producer c . Secondary Carnivores y . First 4 . Cats i v . Primary Consumer d . Transducers z . Second

Options

  1. A1 - i v - c - w ; 2 - i i - d - x ; 3 - i i i - a - y ; 4 - i - b - z
  2. B1 - i - b - x ; 2 - i i i - c - y ; 3 - i i - d - x ; 4 - i v - a - w
  3. C1 - i i i - d - y ; 2 - i v - a - z ; 3 - i - b - w ; 4 - i i - c - x
  4. D1 - i i - a - z ; 2 - i - b - w ; 3 - i v - c - x ; 4 - i i i - d - y

Correct answer

C. 1 - i i i - d - y ; 2 - i v - a - z ; 3 - i - b - w ; 4 - i i - c - x

Step-by-step solution

Grass is at the First Trophic level as it is a producer. It can convert sunlight to chemical energy hence it is a transducer. Grasshoppers (herbivores) eat grass and hence are primary consumer at second trophic level. Rodents eat Grasshoppers and thus are secondary consumers and also primary carnivores at third level. Cats eat Rodents and are Tertiary consumer and secondary carnivores at fourth trophic level.
