    Sunlight
  • What is sunlight absorbed by to be passed on in food chains?
    Photosynthetic organisms (Producers)
  • Why are plants always the first link in food chains?
    They're producers - they convert the energy from the sun into chemical energy (biomass)
  • Why does energy decrease as you go down a food chain?
    It's lost in life processes, (movement, growth, cell repair and reproduction) waste materials and respiration.
  • What is the equation to calculate the efficiency of energy transfers?
    Energy transferred to next level/total energy from previous level X 100
