Question

Quizplus · Accepted Answer

The change in consumer biomass is not used for quantifying primary productivity over time. Primary productivity refers to the rate at which producers (such as plants) convert light energy into chemical energy through photosynthesis. The factors used for quantifying primary productivity over time are the change in producer biomass, the movement of carbon dioxide (which is used in photosynthesis), and the movement of oxygen (which is produced as a byproduct of photosynthesis). The change in consumer biomass is more related to secondary productivity, which refers to the rate at which consumers (such as herbivores) convert primary productivity into their own biomass.
