Question

Which one of the following statements for the pyramid of energy is incorrect, whereas the remaining three are correct?

• A. It is upright in shape
• B. Its base is broad
• C. It shows energy content of different trophic level organisms
• D. It is inverted in shape

Answer 1

The correct option is D It is inverted in shape

An energy pyramid is a graphical model of energy flow in a community. A pyramid of energy is always upright and can never be inverted. Because when energy flows from one trophic level to the next trophic level, some energy is lost as heat at each step. So, the lowest level has the maximum value and highest, lowest value in terms of calories. Each bar in the energy pyramid indicates the amount of energy present at each trophic level at a given time or annually per unit area.
And since the pyramid of energy is upright producers are high in number and hence the base of the energy pyramid is broad. So the statement - pyramid of energy is inverted in shape is the only incorrect statement.
