प्रश्न
If 20000 K Cal energy is available at the level of producers, what will be the amount of energy available at the level of secondary consumers.
उत्तर
According to 10% law of ecology, only 10% of the energy is transferred to each trophic level from the lower trophic level. So the amount of energy available at the secondary level is 20000K Cal × 10% = 2000 K Cal.
