In the equation, GPP - R = NPP , R represents:

In the equation, GPP-R=NPP, R represents:
  1. Radiant energy
  2. Retardation factor
  3. Environment factor
  4. Respiration losses

Solution

The gross primary productivity (GPP) refers to the rate of energy stored by photosynthesis in plants. The R refers to the maintenance and reproduction of plants from the energy expended. GPP minus respiration losses (R) is the net primary productivity (NPP). GPP -R= NPP.
