Primary productivity is the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. It can be divided into gross primary productivity and net primary productivity
The rate of energy production by green plants using organic matter during photosynthesis is called as gross primary production (GPP).
The energy left after respiration and stored as organic matter in the producers is called as net primary production.
Amount of energy available at the consumer level for transfer to the next level is called as secondary productivity.
