Another measure of carbon flow within an ecosystem is net biome productivity (NBP)—the amount of organic matter in a biome minus carbon losses or gains from disturbances such as fire, disease, and human land use. Such disturbances can strongly influence an ecosystem's carbon flows and stocks. Over time, however, disturbance-induced losses ...

We immediately measure the dissolved oxygen (DO) in both bottles and find it is 10 mg/L. We let both bottles sit for one week. After one week, the light bottle has a DO value of 11 mg/L and the dark bottle has a DO value of 5 mg/L. Calculate respiration (R), net primary productivity (NPP) and gross primary productivity (GPP). No. NPP is the energy stored as biomass by plants or primary producers in the ecosystem (or rather the rate at which such energy is stored, if it's productivity you're talking about and it's in gC/m-2/yr-1). Respiration is the energy lost to metabolism or maintenance.

mg/L oxygen in your light bottle. What is the NPP, GPP, and respiration? •NPP = 12 mg/L –10 mg/L = 2 mg O 2 per liter per week •Loss of dissolved O 2 (R) = 10 mg/L –7 mg/L = 3 mg/L/wk •NPP = GPP –R so GPP = NPP + R •GPP = 2 + 3 = 5 mg O 2 /L/wk

Net Primary Productivity (NPP), or the production of plant biomass, is equal to all of the carbon taken up by the vegetation through photosynthesis (called Gross Primary Production or GPP) minus the carbon that is lost to respiration. NPP = GPP - respiration In terrestrial systems, NPP is often calculated by determining the carbon storage ...

Collaborators: Rachel, Amanda, Griffin, Anna, Caroline C., Jared. Introduction/Problem: The gross primary productivity (GPP) of an ecosystem is defined as the rate at which energy is captured during photosynthesis. In other words GPP is the total amount of photosynthetic energy captured in a given period of time.

    Net primary production and allocation. Net primary production (NPP) is the carbon taken up by GPP minus the amount consumed in R a . NPP is a critical quantity because it reflects the amount of carbon removed from the atmosphere by plants integrated over time. 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. GPP has an effect on NPP, but NPP has no effect on GPP.
