Net Primary Productivity (NPP)
Definition
NPP refers to the amount of energy that remains after plants have used some of their captured energy for their own respiration.
Analogy
Think of NPP as your take-home pay after deducting taxes and other expenses from your earnings. It represents the actual usable income you have.
