**Difference between Net Primary Productivity (NPP) and Gross Primary Productivity (GPP)** 1. **Definition**: - **Gross Primary Productivity (GPP)**: This refers to the total amount of organic matter (biomass) produced by photosynthesis in a given area over a specific time period. It represents the total energy captured by plants. - **Net Primary Productivity (NPP)**: This is the amount of organic matter that remains after the plants have used some of the energy for their own respiration. It is calculated by subtracting the energy used in respiration from GPP. 2. **Formula**: - **GPP**: GPP = Total Photosynthesis ...

    [A] : The rate of energy storage at consumer levels are referred to as primary productivities . [R] : Net primary productivity is the total gross productivity and the energy used up in the metabolic process .

    Assertion: Amount of organic matter synthesized by producers per unit time and per unit area during the process of photosynthesis referred to as net primary productivity. Reason: Primary productivity is usually high and sustained throughout the year in temperate areas due to abundance of sunlight.
