Vedclass · Answer

(A) Gross Primary Productivity $(GPP)$ of an ecosystem is the rate of production of organic matter during photosynthesis. Producers (autotrophs) capture solar energy and convert it into chemical energy in the form of organic compounds (glucose). This total amount of organic matter synthesized per unit area over a time period is known as $GPP$. Part of this $GPP$ is utilized by producers for their own respiration $(R)$,and the remaining energy is stored as Net Primary Productivity $(NPP)$,where $NPP = GPP - R$.

Gross Primary Productivity $(GPP)$ is defined as:
