The correct Answer is:
To answer the question regarding the accuracy of biomass measurement, we can follow these steps: ### Step-by-Step Solution: 1. **Define Biomass**: Biomass refers to the total mass of living matter in a given area or volume. It can be measured in terms of fresh weight or dry weight. 2. **Understand Fresh Weight vs. Dry Weight**: - **Fresh Weight**: This is the weight of the biomass including all water content. It can vary significantly due to changes in water content, making it less reliable for accurate measurements. - **Dry Weight**: This is the weight of the biomass after all water has been removed. It provides a more stable and consistent measure since it is not influenced by water content. 3. **Importance of Dry Weight**: - Dry weight is considered a more accurate representation of biomass because it reflects the actual organic material present without the variability introduced by water content. - Since water content can fluctuate, using dry weight allows for more precise comparisons between different samples or conditions. 4. **Conclusion**: Therefore, when measuring biomass, the dry weight is the preferred method for accuracy. 5. **Final Answer**: The measurement of biomass is more accurate in terms of dry weight.
