Question

The rate of formation of new organic matter by consumers, and the biomass available for consumption of herbivores as well as decomposers, are referred to as:

• A. Gross primary productivity and Net primary productivity
• B. Net primary productivity and Secondary productivity
• C. Secondary productivity and Gross primary productivity
• D. Secondary productivity and Primary productivity

Hint:

Productivity explained:
GPP: Energy captured by producers.
NPP: GPP minus the energy used in respiration.
Secondary productivity: Biomass generated by consumers.

Answer 1

The Correct Option is C

Gross primary productivity (GPP) refers to the total energy captured by autotrophs. Secondary productivity is the biomass created by consumers from the organic matter they consume.
