Question

Write an equation here that shows the relationship between gross and net primary production.

Answer 1

Net Primary Production = Gross Primary Production - Respiration

Step-by-step explanation:

1. Gross Primary Production (GPP) = The total amount of chemical energy that is expressed as carbon biomass created by primary producers in unit time.
2. Respiration (R) = A fraction of fixed amount of energy that is used by primary producers for the cellular respiration and maintenance of existing tissues.
3. Net Primary Production (NPP) = The remaining amount of the fixed energy.

Therefore, the equation that shows the relationship between gross and net primary production is,

Net Primary Production (NPP) = Gross Primary Production (GPP) - Respiration (R)

Net primary production is the amount of energy that remains behind after the consumption of some fraction of energy in respiration from the gross primary production.
