Question

The number of individuals at the trophic level decreases from the producer level to the consumer level in

• A. The pyramid of number
• B. The pyramid of biomass
• C. The pyramid of energy
• D. None of the above

Answer 1

Answer: (C)

Pyramid of energy is a graphic representation of flow of energy in different trophic levels. It is always upright because only 10% of energy transferred from one trophic level to another. The energy level is maximum at the organisms occupying the base of the energy pyramid i.e., the producers and they are the most numerous organisms, while the consumers occupying the higher levels have less energy. As energy content keeps on decreasing so the number of organisms also decrease, at higher levels.
