What is Gross primary production?
The rate at which an ecosystems producers covert solar energy into chemical energy (in the form of biomass). To Solve : GPP = NPP + R (R - Respiration)
What is the difference between net productivity and gross productivity?
Gross primary production consists of the amount of light energy that is converted to chemical energy by photosynthesis per unit of time. This chemical energy is going to two places-- respiration and growth of new biomass. Net primary production omits the energy used in respiration... just the energy going to new plant growth. Mathematically: (R = respiration) NPP = GPR - R
What is gross production?

What is the primary measure of a country's development?
per capita gross domestic product
How do capital goods affect the GDP?
Investing in capital goods can increase productivity and / or workforce. These can affect the Gross Domestic Product if quality or number of products increase consequently.
Equals the gross primary productivity minus the respiration rate of producers?
net
What is the primary productivity rate at which producers in an ecosystem carry on photosynthesis to make carbohydrates?
Gross
What is the difference between net primary productivity and primary productivity?
primary productivity is defined as the amount of . organic matter produced per unit area over a time period by plant during photosynthesis. and gross primary productivity minus respiration losses is the net primary productivity .
What is the difference between gross primary productivity and net primary productivity?
Gross primary production consists of the amount of light energy that is converted to chemical energy by photosynthesis per unit of time. This chemical energy is going to two places-- respiration and growth of new biomass. Net primary production omits the energy used in respiration... just the energy going to new plant growth. Mathematically: (R = respiration) NPP = GPR - R
How are gross and net primary productivity of a community related?
Gross Primary Productivity- Total amount of chemical energy stored by photosynthesis. Net Primary Productivity- Remaining energy, which is available to the consumers as food.

How do you calculate NPP?
GPP (gross primary production) minus cellular respiration.
What statement is correct with respect to gross primary productivity?
the amount of carbon dioxide that the plants release.
What is the difference between GPP and NPP?
Gross primary production (GPP) is the rate at which an ecosystem's producers capture and store a given amount of chemical energy as biomass in a given length of time. Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").[1] The remaining fixed energy (i.e., mass of photosynthate) is referred to as net primary production (NPP).NPP = GPP - respiration [by plants]Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (GPP) and the rate at which they use some of that energy during respiration. Some net primary production goes toward growth and reproduction of primary producers, while some is consumed by herbivores.Both gross and net primary production are in units of mass / area / time. In terrestrial ecosystems, mass of carbon per unit area per year (g C/m2/yr) is most often used as the unit of measurement.
Why is an ecosystem's net primary production (NPP) lower than its gross primary production (GPP)?
Net primary production (NPP) is lower than gross primary production (GPP) because not all of the energy captured through photosynthesis is available for growth and reproduction. Some of the energy is used by plants for their own metabolic processes, such as respiration. Additionally, a portion of the energy is lost as heat during these metabolic processes. Therefore, NPP represents the amount of energy available for consumption by herbivores and higher trophic levels.
