NEET 2024 Botany Energy Flow MCQ Question
In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is 100x (kcal m⁻²) yr⁻¹, what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?
10x (kcal m⁻²) yr⁻¹
100x/3 (kcal m⁻²) yr⁻¹
x/10 (kcal m⁻²) yr⁻¹
x (kcal m⁻²) yr⁻¹
Correct Answer
Detailed Explanation
The energy transfer between trophic levels is typically about 10%. Thus, the GPP at the third trophic level would be approximately 10% of the NPP of the first trophic level.
