Concepts of biomass and net primary production.

• What is biomass?:

  • The mass of living material of the organism measured in kg/m2
• What is biomass?:

  • The mass of living material of the organism measured in kg/m2
• What is net primary production?:

  • Net primary production (NPP) is a measure used to show the productivity of local ecosystems or biomes
  • It is the rate at energy is stored as biomass
  • The most productive biome is the tropical rainforest with a figure of around 2000 . This is compared to deserts with an average NPP of around 3.
• What is net primary production?:

  • Net primary production (NPP) is a measure used to show the productivity of local ecosystems or biomes
  • It is the rate at energy is stored as biomass
  • The most productive biome is the tropical rainforest with a figure of around 2000 . This is compared to deserts with an average NPP of around 3.
• NPP formula:

  A) gross primary production

  B) -

  C) respiratory loss
