- What is Primary Production and what are the factors that limit primary production in terrestrial and aquatic ecosystems. Give examples of where some of the most productive systems are on land and in water. Distinguish between Gross Primary Productivity and Net Primary ProductivityDistinguish between gross primary production and net primaryproduction.Net primary productivity refers to the rate of energy storage as organic matter by autotrophs after respiration is deducted the total rate of photosynthesis, or energy assimilated, by autotrophs the amount of accumulated organic matter found in an area at a given time the production of new tissues and offspring by heterotrophs
