Primary producers (usually plants and other photosynthesizers) are the gateway for energy to enter food webs. Productivity is the rate at which energy is added to the bodies of a group of organisms (such as primary producers) in the form of biomass. Gross productivity is the overall rate of energy capture. Net productivity is lower, adjusted ...
