The pyramid will never be inverted since it is based on the amount of energy per unit area that flows through the trophic level of the food chain in a given amount of time. 

To make a pyramid of energy, you need to find out how much energy an organism contains and how many organisms there are in a trophic level. The amount of energy in an organism can…
