Answer: Option A
Solution:
The rate at which the chemical energy is stored by plants is known as Gross primary productivity.Gross primary production (GPP) is the amount of chemical energy, typically expressed as carbon biomass, that primary producers create in a given length of time. It is the total rate at which material is produced.
Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues.
