Question

Biomass available for consumers and the rate of formation of new organic matter by consumers are respectively:, Gross primary productivity and net primary productivity, Net primary productivity and gross primary productivity, Gross primary productivity and secondary productivity, Net primary productivity and secondary productivity

MARKS App · Accepted Answer

Total biomass produced by producers is called gross primary productivity (GPP). In producers, some energy or biomass is utilized in respiration and other metabolic processes, so available biomass to next trophic level i.e. primary consumers are called net primary productivity (NPP). In these consumers, some amount of biomass is utilized in respiration and other metabolic processes and the remaining amount is assimilated in tissues, which is called as secondary productivity.
