• A. Energy
• B. Biomass
• C. All of the above
• D. Number

Answer 1

Answer: (A)

Pyramid of energy can never be inverted. This is because at each tropic level, as one moves from producers to primary consumers to secondary and tertiary consumers, the amount of available energy goes on reducing. According to the 10% law, at each tropic level, only 10% of the energy of the tropic level is transferred.

So, option B " Energy" is the correct answer.
