NEET Botany MCQs

In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is 100x(kcalm^–2)yr^–1, what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?

• 10x(kcalm^–2)yr^–1
• 100x/3x(kcalm^–2)yr^–1
• x/10(kcalm^–2)yr^–1
• x(kcalm^–2)yr^–1
