Question

The diagram below represents a biomass pyramid.

Which statement concerning the energy in this pyramid is correct ?

• A. The producer organisms contain the least amount of stored energy.
• B. Stored energy decreases from consumer 3 to consumer 2.
• C. Consumer 3 contains the least amount of stored energy.
• D. Stored energy increases from the producer to consumers 1.

Answer 1

Answer: (C)

Consumer 3 contains the least amount of stored energy.

The amount of energy flow decreases with every successive trophic level and only 10% is passed to the next level as useable biological energy and the rest 90% is utilized and stored by the organisms of the previous trophic level and some amount is lost during the transfer. As consumer 3 is at the top therefore will have least amount of stored energy.

So, the correct answer is option C.
