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
is net invesment = gross investment - depreciation

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 .
Gross margin is Gross income as a percentage of revenue. Net Margin is net income as a percentage of revenue.
Gross = Before TaxesNet= After Taxes
The difference between gross pay and net pay is that gross pay is the amount that you receive before tax deductions and pay net is the money you take home after all the tax deductions

The difference between a gross and net withdrawal from a fund has to do with how much money you will receive. The gross withdrawal is the amount taken out of your fund which includes fees that you will not get to keep, the net withdrawal is the amount you receive after the bank's fees and any others are taken out.
Gross primary productivity is the total amount of energy captured by producers through photosynthesis, while net primary productivity is the amount of energy left after subtracting energy used for respiration. Net primary productivity is thus derived from gross primary productivity, as it represents the energy available to consumers in the community after accounting for producers' own energy needs.
Gross Primary Productivity (GPP) is the total amount of energy that plants capture through photosynthesis, while Net Primary Productivity (NPP) is the amount of energy that plants store after accounting for the energy they use for their own growth and metabolism. In other words, GPP is the total production of plants, while NPP is the amount of energy available for consumption by other organisms in the ecosystem.
