The correct Answer is:
To determine the biomass of the tiger in the food chain "Grass to Deer to Tiger," we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Biomass of Grass**: - The biomass of grass is given as 1 tonne, which is equivalent to 1000 kg. 2. **Apply the 10% Rule**: - According to the 10% rule in ecology, only 10% of the biomass from one trophic level is transferred to the next trophic level. This means that when herbivores (like deer) consume the grass, they only gain 10% of the biomass of the grass. 3. **Calculate the Biomass of Deer**: - From the grass biomass of 1000 kg, the biomass available to the deer (the primary consumer) will be: \[ \text{Biomass of Deer} = 10\% \text{ of } 1000 \text{ kg} = 0.1 \times 1000 \text{ kg} = 100 \text{ kg} \] 4. **Calculate the Biomass of Tiger**: - Now, applying the 10% rule again for the tiger (the secondary consumer), which eats the deer: \[ \text{Biomass of Tiger} = 10\% \text{ of } 100 \text{ kg} = 0.1 \times 100 \text{ kg} = 10 \text{ kg} \] 5. **Conclusion**: - Therefore, the biomass of the tiger in this food chain is 10 kg. ### Final Answer: The biomass of the tiger will be **10 kg**. ---
