Options

  1. A(A)-(II), (B)-(III), (C)-(I), (D)-(IV)
  2. B(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
  3. C(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
  4. D(A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Correct answer

C. (A)-(II), (B)-(IV), (C)-(I), (D)-(III)

Step-by-step solution

According to the principles of ecological pyramids: (A) The pyramid of energy is always upright (II) because energy is continuously lost as heat at each successive trophic level. (B) The pyramid of biomass in a sea is generally inverted (IV) because the biomass of fishes far exceeds that of the phytoplankton they depend on. (C) The pyramid of numbers in a grassland is upright (I) as the number of producers (grasses) is much higher than the number of herbivores and carnivores. (D) The pyramid of numbers in a tree ec
