(B) In the study of ecosystem productivity,$GPP$ stands for Gross Primary Productivity,which is the total rate of production of organic matter during photosynthesis.$NPP$ stands for Net Primary Productivity,which is the amount of biomass available for consumption by heterotrophs.$R$ represents the respiration losses,which is the energy used by plants for their own metabolic activities.The relationship is defined as $NPP = GPP - R$.

In the equation $GPP - R = NPP$,what does $R$ represent?
