Hi Beena,

NPP is Net Primary Productivity.

To understand that, you first have to understand Primary Productivity which is, - The amount of biomass or organic matter produced per unit area over a time period in plants during photosynthesis. It expressed in terms of weight (gm-2) or energy (kcal m-2).

It is of two types :

GPP and NPP

Gross Primary Productivity: It is the rate of production of organic matter during photosynthesis in an ecosystem. It is utilized by plants for respiration and some are passed to the next trophic level. 

Net Primary Productivity: It is the weight of the organic matter stored by the producers in a unit area/volume per unit time. It is utilized by Heterotrophs.

NPP = GPP - R  (R = Respiration losses)
