Question

The amount of energy ________ from higher trophic to lower trophic levels.

• A. Increases
• B. Decreases
• C. Remains the same
• D. Cannot be predicted

Answer 1

The correct option is A

Increases

The correct answer is A.

Explanation for correct option:

1. If we consider the pyramid of energy, it is always upright in which producers(plants) are present at the base or lowest trophic level which is followed by primary(herbivore), secondary(carnivore) and finally tertiary consumers(carnivore).
2. The solar energy is maximum absorbed by the plants which produce the highest energy and then only 10% of energy is transferred to the further trophic level.
3. The tertiary consumers get the least amount of energy as compared to the primary consumers.
4. Thus, the amount of energy increases from higher trophic to lower trophic levels.

Explanation for incorrect options:

Option B:

1. The amount of energy decreases as we move from lower trophic to higher trophic levels.

Final answer: The amount of energy increases from higher trophic to lower trophic levels.
