What is the difference between gross primary productivity and net primary productivity quizlet?

What is the difference between net and gross primary production production? Net primary production is equal to gross primary production minus energy used by primary producers for respiration. Gross primary production is the amount of energy from light converted to chemical energy per unit of time.

What is the difference between GPP and NPP quizlet?

Explanation. A) Gross primary production is the total amount of energy from light that is transformed to chemical energy in a unit of time while a net primary production is gross primary production minus the rate at which they utilize energy during respiration.

What is the relationship between net primary productivity and gross productivity write the equation?

You can see that your bank account balance is determined as follows: Your Net production is equal to your Gross Production minus Respiration, which is the same as the equation above that states the Net Primary Production (NPP) = the Gross Primary Production (GPP) minus Respiration (R).

What is net primary production?

Net primary production (NPP) is strictly defined as the difference between the energy fixed by autotrophs and their respiration, and it is most commonly equated to increments in biomass per unit of land surface and time.

What is the difference between gross and net productivity?

“GPP” stands for “Gross Primary Productivity” while “NPP” stands for “Net Primary Productivity.” 2. GPP is the rate an ecosystem's primary producers collect and save biomass in a specified time for chemical, thermal, and biochemical conversion while NPP is the rate of loss or excess that is generated by the process.

How does gross primary production differ from net primary production what are the two components of gross primary production and how do they differ?

While gross primary production (GPP) is the total influx of carbon into an ecosystem through the photosynthetic fixation of CO2, net primary production (NPP) is this gross carbon influx discounted for plant respiratory costs of growth and maintenance.

What is GSP and NSP?

Gross secondary productivity(GSP): is gained through absorption in consumers. Net secondary productivity(NSP): The gain by consumers in energy or biomass per unit area per unit time remaining after allowing for respiratory losses.

What does the difference between gross primary production GPP and net primary production NPP represent?

What is net primary productivity NPP?

Definition. The amount of carbon retained in an ecosystem (increase in biomass); it is equal to the difference between the amount of carbon produced through photosynthesis (GPP) and the amount of energy that is used for respiration (R).

What is net primary productivity or NPP?

What is net productivity?

Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it's the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

What is the difference between primary productivity and secondary productivity?

b) Define food web….

Primary productivity	Secondary productivity
The energy is obtained from the sunlight and food is produced.	The energy is obtained by the transfer of the energy through food chain.
The process of production is fast.	The process of production is quite slow.

What is net primary productivity NPP )? Quizlet?

What is net primary productivity (NPP)? The quantity of biomass potentially available to consumers in an ecosystem. How is net primary productivity meausured? It is measured in unit of mass or energy per unit area per unit time.

What is the difference between primary and secondary productivity in the ecosystem?

So, the primary productivity is the production of organic matter by the producers while secondary productivity is the production of the organic matter by the consumers.

How are gross and net production different?

Gross production is the total amount a firms produces, while net production subtracts all the costs the firm has incurred.

What is NPP and GPP in ecosystem?

Gross primary productivity (GPP) is the rate of photosynthesis. Net primary productivity (NPP) is the rate of storage of organic matter except which is utilized for the respiration by plants. Hence, we can say that NPP = GPP – plant respiration.

What is the difference between net productivity and gross productivity?

What defines the difference between primary and secondary production?

The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.

How would you differentiate between gross primary productivity from net primary productivity and secondary productivity of an ecosystem?

Net primary productivity (NPP) is the rate at which all plants in an ecosystem produce net useful chemical energy. While gross primary productivity (GPP) is the rate at which primary producers save and collect biomass for energy conservation. NPP is the difference between GPP and cellular respiration.

What’s the difference between primary productivity and secondary productivity?

So, the primary productivity is the production of organic matter by the producers while secondary productivity is the production of the organic matter by the consumers.

What is the difference between gross and net production?

Gross domestic product is the total value of a nation's output of goods and services. Net domestic product is what is left of GDP after the depreciation of the nation's capital stock.

What defines the difference between primary and secondary production quizlet?

Primary succession; where rebuilding begins in a practically lifeless area where there is no soil, such as on a new volcanic island or on rubble left by retreating glacier. Secondary succession; where rebuilding begins in a place where there was little disturbance which still left the soil intact.

Whats the difference between gross primary production and net primary production?

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.

What is the definition of primary productivity what units are used to measure primary productivity?

Primary Productivity. gain of new biomass or energy by PRODUCERS per unit area per unit time (photosynthesis) Secondary Productivity. the biomass gained by CONSUMERS per unit area per unit time (FEEDING OR ABSORPTION)

What is produced in primary productivity quizlet?

Primary production is the chemical energy generated by autotrophs during photosynthesis and chemosynthesis. -autotrophs: organisms that convert energy from sunlight or inorganic compounds into chemical energy–stored in C-C bonds.
