  1. Flow of Energy Through The BIOSPHERE

  2. Importance of Solar Energy • All Organisms require energy for metabolism • The original source of energy in the biosphere is the Sun

  3. Producers • Organisms that are capable of trapping solar energy to produce food (carbohydrates) • Also called Autotrophs

  4. Producers (cont.) • Along with producing their own food, producers are a source of food energy for all other living organisms

  5. Consumers • Organisms that get food energy by feeding off of other organisms • Also called heterotrophs

  6. Food Chains • As one organism feeds off of another the energy within the organism being fed on is transferred to the feeder, this is referred to as a FOOD CHAIN

  7. Feeding Levels within a food chain • Producers • 1st order consumers • 2nd order consumers • 3rd order consumers

  8. Example of A Basic Food Chain

  9. Food Webs • In an ecosystem there are many food chains • Usually the organisms found in one food chain are also a part of another food chain. • Several interconnected food chains are called Food Webs

  10. Example of a Food Web

  11. Energy Transfer • As energy is transferred from one organism to another in a food chain or web, a large fraction of the original energy is lost

  12. Energy Transfer (Continued) • Only 10% of the original amount of energy is passed from one trophic level to the next • This energy loss can be represented by a Pyramid of Energy

  13. Pyramid of Energy

  14. Pyramid of Energy (Continued) • At each level of the pyramid the smaller space represents the lesser amount of energy

  15. Pyramids of Numbers • Same as the pyramid of energy but represents the fact that there are fewer individuals at each successive feeding level

  16. Pyramid of Biomass • Represent the fact that there is less total mass found in each successive level
