What term describes the total energy fixed by plants through photosynthesis, minus the energy used for their own respiration?
Answer:
gross primary production
There is a potential conflict in terminology here. Gross Primary Production (GPP) is the total energy fixed, while Net Primary Production (NPP) is the energy remaining after respiration. The source answer 'A' may be technically inaccurate if it refers to the net amount, but it is preserved as requested.
