Which of the following equations is correct? A) NPP = GPP - RB) R = NPP + GPPC) GPP = NPP - RD) NPP = GPP + RE) NPP = GPP/R

A) NPP = GPP - R

Explanation:

NPP is the abbreviation of net primary productivity while

GPP is the abbreviation of gross primary productivity and

R is used for Respiration.

NPP = GPP - R

The equation used to determine the overall productivity of a system where the NPP or Net Primary Production is equal to the GPP Gross Primary Production minus the R or Respiration.

The NPP determines the plants overall efficiency in the ecosystem.
