Net Primary Production = Gross Primary Production - Respiration
Explanation:
<u>Gross Primary Production (GPP)</u> = The total amount of chemical energy that is expressed as carbon biomass created by primary producers in unit time.
<u>Respiration (R)</u> = A fraction of fixed amount of energy that is used by primary producers for the cellular respiration and maintenance of existing tissues.
<u>Net Primary Production (NPP)</u> = The remaining amount of the fixed energy.
Therefore, the equation that shows the relationship between gross and net primary production is,
<em>Net Primary Production (NPP) = Gross Primary Production (GPP) - Respiration (R)</em>
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.
The two main plant tissue that works together to release sugar and carry hormones so that reproduction can take place are: The ground and the vascular tissue.
