What do you understand by primary and secondary productivity?

  • Primary productivity: The rate at which autotrophic organisms produce organic compounds in an ecosystem is known as primary productivity. It can be of two types: 
      • Gross Productivity: It is the total solar energy trapped during photosynthesis.
      • Net Productivity: It is the rate at which energy is stored by the producers as biomass. This energy is made available to the consumers who feed on the producers.
  • Secondary productivity: It refers to the rate of biomass formed by the heterotrophs such as grazers and decomposers.
