260240 In the equation $GPP - R = NPP$
GPP is Gross Primary Productivity
NPP is Net Primary Productivity $R$ here is

1 Reproductive allocation

2 Photosynthetically active radiation

3 Respiratory quotient

4 Respiratory loss

Explanation:

In the ecosystem the energy of sun helps the plants to produces their own food through the process of photosynthesis. During this process, the plants inorganic material to organic compound.
The total energy produce by plant is called (GPP) Gross primary productivity.
The remaining energy after use of energy as respiration energy is known as net primary productivity (NPP).
- The amount of energy and biomass in the producers of food chain is $100 %$ at each successive levels.
The organisms at each level use energy for respiration this is called respiration loss.
$NPP = GPP - R$
