NEET Botany Energy Flow MCQ Question
If the biomass at the producer level in a grassland ecosystem is 10,000 kg, and the biomass decreases by 90% at each successive trophic level, what is the biomass at the tertiary consumer level?
10 kg
100 kg
1 kg
1000 kg
Correct Answer
Detailed Explanation
The biomass decreases by 90% at each trophic level. Therefore, at the tertiary consumer level, it is 10% of the secondary consumer's biomass, which is 10% of the primary consumer's biomass, which is 10% of the producer's biomass, resulting in 10 kg.
