How are gross production and net production different?

Gross production refers to the total amount of energy or biomass produced by organisms through processes like photosynthesis, without accounting for any energy used in respiration. In contrast, net production is the energy or biomass that remains after subtracting the energy used for respiration and other metabolic processes. Essentially, net production represents the actual growth available for consumption by other organisms in the ecosystem. This distinction is crucial in understanding energy flow and productivity within ecological systems.
