WebOn average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers. Put another way, net productivity usually drops by a factor of ten from one trophic level to the next. WebProtocol Author Amy Davidson Definition Dry weight biomass measurements with electronic balance Overview Total dry mass is often used as an indication of plant fitness. In particular, dry vegetative mass is generally correlated to reproductive mass. In addition, the plant samples may be split into leaves, stems and roots. This enables calculation of the…
