Question
__________ is utilized by plants during respiration.
- NPP
- GPP
- Respiration loss
- Energy
Hint:
Gross primary production (GPP) is utilized by plants during respiration.
The correct answer is: GPP
- Gross primary production (GPP) is the total amount of carbon dioxide "fixed" by land plants per unit of time through the photosynthetic reduction of CO2 into organic compounds.
- It is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration
