how to measure biomass in an ecosystem - Axtarish в Google
We can directly measure the biomass by burning a sample of the organism in a calorimeter . The sample has to be dry. We can measure the energy released during burning. We can estimate the chemical energy store by measuring the amount of energy released (in J or kJ) during burning.
