The net primary productivity (NPP) of an ecosystem is 1 kg C/m²/year, and the energy needed by the producers for their respiration is 1.5 kg C/m²/year. The gross primary productivity (GPP) of such an ecosystem would be:

• 0.5 kg C/m²/year

• 1.0 kg C/m²/year

• 1.5 kg C/m²/year

• 2.0 kg C/m²/year

• 2.5 kg C/m²/year
