What is the difference between Gross and Net Productivity?

Productivity is the rate of biomass generation in an ecosystem. Several factors affect GPPS and NPP which include climate, water, soil type and also nutrient, etc.

GPPS stands for gross primary productivity. Gross primary productivity can be defined as the rate at how autotrophs in the ecosystem collect and save a certain amount of chemical energy. Some of the energy produced in GPPS is used for chemical, thermal and biochemical conversion. Also, part of the energy is used by primary producers to convert nutrients and also adenosine triphosphate.

NPP stands for net primary productivity. The excess or loss of generated from gross primary productivity is called net primary productivity. The net primary productivity is used to access the effect of climate change on the function of the ecosystem.

When you say gross productivity, you are referring to the rate of energy capture. This is referring to the total rate that the material has already been produced. Net productivity, on the other hand, is going to be lower.

Net productivity refers to the adjusted amount of gross productivity for the organisms that are undergoing metabolism or respiration. This will reflect the amount of energy that has been stored as biomass. If you would like to understand it further, NPP is going to be the gross productivity minus the rate of respiration or metabolism. Net productivity is also more focused on ecosystem conditions.
