Measure consistently
Water content varies widely among organisms and conditions. Dry weight reduces this variability and gives a more comparable estimate of biomass.
OlympIQ exam lens
- ✓Biomass is living organic matter.
- ✓Dry mass avoids variable water content.
OlympIQ trap
Standing crop is a mass at a moment, not an energy flow per time.
