SPEC 7- ENERGY TRANSFER AND PRODUCTIVITY

Key Terms:

  • Gross Productivity- the amount of energy taken in by ORGANISM. 
  • Net Productivity- The amount of energy available for the next trophic level
  • Gross Primary Productivity- The total biomass produced energy taken in by PLANTS - by Photosynthesis.The Biomass production is reduced by respiration.
  • Net Primary Productivity- The rate of production of a new biomass that is available to the next trophic level. 

Key Equations:

  • Respiration = Gross primary productivity - Net primary productivity
  • Gross primary productivity= Net primary productivity + Respiration
  • Energy efficiency= (Current Trophic Level/ Previous Trophic
