How is GPP different from NPP?

How is GPP different from NPP?

Key Differences GPP stands for gross primary productivity while NPP stands for net primary productivity. GPP is the total amount of energy produced in the process, whereas NPP is the total difference between GPP and the energy used by the producer for respiration.

How are GPP and NPP related?

NPP is defined as the loss or excess of energy which is generated by the process while GPP is the rate at which primary producers save and collect biomass for energy conversion. NPP is the difference between GPP and cellular respiration. On the other hand, GPP is used for cell production.

What is the GPP?

Gross primary productivity, or GPP, is the rate at which solar energy is captured in sugar molecules during photosynthesis (energy captured per unit area per unit time). Producers such as plants use some of this energy for metabolism/cellular respiration and some for growth (building tissues).

What does a high NPP mean?

NPP and ecosystem implications NPP is the net energy available after respiration. The higher the net primary production, the more animals can be supported per unit area. In most natural ecosystems, high net primary production is generally accompanied by a highly diverse plant and animal community.
