  • Gross Productivity
    Total energy initially captured by an organism, representing the starting point for energy flow in ecosystems.
  • Gross Primary Productivity
    Total energy captured by primary producers, often nearly equal to the energy they can use due to minimal waste.
  • Gross Consumer Productivity
    Total energy captured by consumers from their food, before accounting for losses as waste and heat.
  • Assimilated Energy
    Portion of captured energy actually used by an organism for cellular respiration and biomass production.
  • Biomass
    Total mass of living matter, either for an individual or a group, available for growth, reproduction, or consumption.
  • Net Productivity
    Energy available for new biomass after subtracting respiration from assimilated energy; supports the next trophic level.
  • Net Primary Productivity
    Amount of energy in primary producers available for growth and consumption by higher trophic levels.
  • Net Consumer Productivity
    Energy in consumers available for their growth and for transfer to organisms at higher trophic levels.
  • Respiration
    Process using assimilated energy for metabolic needs, resulting in energy loss as heat and not available for biomass.
  • Net Production Efficiency
    Percentage of assimilated energy converted into new biomass within a single organism or trophic level.
  • Trophic Efficiency
    Percentage of energy transferred from one trophic level’s net productivity to the next, typically around 10%.
  • Trophic Level
    Position in a food chain, such as primary producer or consumer, indicating an organism’s role in energy transfer.
  • Secondary Productivity
    Alternative term for consumer productivity, focusing on energy captured and used by consumers.
  • Energy Efficiency
    Measure of how effectively energy is used or transferred within an ecosystem, encompassing several efficiency types.
