Study Notes

  • An energy pyramid is a graphical representation of energy flow in a community, displaying different groups of organisms at various levels
  • Producers, such as plants, are at the bottom of an energy pyramid. They use sunlight and photosynthesis to produce glucose, which can be converted to energy
  • Plants take in sunlight, carbon dioxide, and water to produce glucose and oxygen
  • Herbivores, or primary consumers, are the next layer in the energy pyramid. They consume producers, such as plants
  • Carnivores and omnivores make up the secondary consumers level, consuming primary consumers. Examples include frogs, lizards, snakes, and many birds
  • Tertiary consumers, the third level, consume secondary consumers. Carnivores fall into this category, such as wolves, lions, and hawks
  • Each layer of the energy pyramid is called a trophic level
  • Only 10% of energy is transferred from one trophic level to the next, with 90% being lost, mostly as heat.
