Question

The biomass available for consumption to heterotrophs and the rate of formation of new organic matter by consumers are defined as

• A. Net primary productivity and secondary productivity, respectively
• B. Gross primary productivity and net primary productivity, respectively
• C. Net primary productivity and gross primary productivity, respectively
• D. Gross primary productivity and secondary productivity, respectively

Answer 1

The correct option is A

Net primary productivity and secondary productivity, respectively

The amount of organic matter stored by the producers and is available for the heterotrophs is called net primary productivity (NPP), and the rate of resynthesis of organic matter by the consumers is known as secondary productivity.
