Primary productivity tends to decline with ___ in aquatic systems. The productivity of autotrophs that create their biomass without consuming other organisms forms the basis of the food chain and modifies the atmosphere making life on earth possible for heterotrophs that either feed directly off autotrophs or consume the organisms that do so. Most primary productivity in the oceans is carried out by free-floating phytoplankton in the open ocean rather than by bottom-dwelling (benthic) plants, with chemoautotrophs contributing smaller amounts as producers in deep-sea-vent habitats. It refers to the total productivity including the energy utilized for respiration by the producers 3. All the factors, which are related to input and output components of a production process, are likely to affect Productivity. Y    Compare SECONDARY PRODUCTION.
