ENERGY TRANSFER

  • Producers use energy from sunlight to make molecules of sugar.
  • Consumers use this sugar as a form of chemical energy to do work.
  • Every time energy is transferred within an ecosystem, some energy changes form.
  • Not all of the chemical energy (food) that a plant creates can reach the animal that eats it.
  •  In every ecosystem, there is less energy available to secondary consumers than primary consumers.
