High net primary productivity

Previous Previous Next Next
Description
Biomass = organic material of which living organisms are formed

Gross primary production (GPP) = assimilation of energy by autotrophs

Primary production = conversion of solar energy to chemical energy by autotrophs

Net primary production (NPP) = energy remaining  after respiration, and is used to generate biomass
Available for heterotrophs

Secondary production = biomass generated by heterotrophs

Productivity = rate at which ecosystems generate biomass
Freshwater wetlands, tropical forests, coral reefs, and algal beds have highest net primary productivity

High net primary productivity = ecosystems whose plants rapidly convert solar energy to biomass
