Question:

Arrange the amount of energy in a sequence from the highest trophic level to the lowest trophic level (Pyramid of Energy):

(A). 10,000 J

(B). 1000 J

(C). 10 J

(D). 100 J

Choose the correct answer from the options given below:

Options:

(A), (B), (D), (C)

(A), (C), (B), (D)

(C), (D), (B), (A)

(C), (B), (D), (A)

Correct Answer:

(C), (D), (B), (A)

Explanation:

The correct answer is Option (3) → (C), (D), (B), (A)

In a Pyramid of Energy, energy decreases as you move up the trophic levels because only about 10% of energy is transferred from one level to the next — the rest is lost as heat or used for metabolism.

Arranged from Highest Trophic Level to Lowest Trophic Level:

(C). 10 J – Top-level consumers (Tertiary consumers)
(D). 100 J – Secondary consumers
(B). 1000 J – Primary consumers (Herbivores)
(A). 10,000 J – Producers (Plants, algae)
