Answer:
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.

Humans can will themselves to eat more, as we know that food comes easy to us.
Animals, on the other hand, top priority is survival, so they usually wouldn't think about eating more because it just "tastes good."
