Question

PLEASE HELP :) What is the difference between Gross Primary Production and Net primary production in simple terms? (If you could also provide an example I would really appreciate it.) Thank you for your time!

Answer 1

Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. ... Net primary production is directly related to ecosystem conditions.
