How are gross production and net production different? a. net production is always greater than gross production. b. net production is always less than gross production. c. only animals have net production. d. only plants have net production.

The answer is b. Net production is always less than gross production. Primary production in ecology is the production of organic compounds through the process of photosynthesis in producers (plants). Gross production is the amount of produced organic compounds by producers. Net production is the amount of stored organic compounds by producers. Net production is always less than gross production because plants cannot store more organic compounds than they are produced.
