Question

Which energy pyramid cannot be inverted?

Answer 1

Please clarify your question

Answer 2

Because in the pyramid of energy the 1st(bottom level) passes on 10% of the energy to the next, and that level passes only 10% of the energy to the 3rd level. If it was inverted it would be impossible to pass up energy up because there would be almost no energy to begin with therefore making it inefficient.
