In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is \( 100x \text{ (kcal m}^{-2}\text{) yr}^{-1} \), what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?

1. A
   \( 10x \text{ (kcal m}^{-2}\text{) yr}^{-1} \)
2. B
   \( \frac{100x}{3x} \text{ (kcal m}^{-2}\text{) yr}^{-1} \)
3. C
   \( \frac{x}{10} \text{ (kcal m}^{-2}\text{) yr}^{-1} \)
4. D
   \( x \text{ (kcal m}^{-2}\text{) yr}^{-1} \)
