NEET Biology question
Refer to the given energy pyramid (values in kcal/m²/yr, bottom to top): Solar radiation (IV) → Primary producer (III, 1000) → Primary consumer (II, 100) → Top consumer (I, 10).
The ecological efficiency at the primary consumer level, in comparison to that at the secondary consumer level, is
Answer: (C)
Solution
Ecological efficiency = (energy in biomass production at a trophic level ÷ energy in biomass production at the previous trophic level) × 100. Since the energy available at the producer level (the previous level for the primary consumer)
