Identify the statements which hold true with respect to the above figure ?
(A) The figure shows the pyramid of biomass.
(B) The value of 'D' will always be lower than 'A' in grassland ecosystem.
(C) The energy at 'A' is higher than the energy at 'D'.
(D) The energy at 'D' is higher than the energy at 'A'.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (B) and (C) only
(A) The figure shows the pyramid of biomass. — Incorrect. The values count individuals; it is a pyramid of numbers.
(B) The value of ‘D’ will always be lower than ‘A’ in grassland ecosystem. — Correct. In a grassland there are always far fewer top carnivores than grass plants.
(C) The energy at ‘A’ is higher than the energy at ‘D’. — Correct. Only about 10 per cent of energy passes from one level to the next, so the producers hold the most.
(D) The energy at ‘D’ is higher than the energy at ‘A’. — Incorrect. The reverse of (C).
