Presentation Transcript

  1. The Energy Pyramid • Producer – a plant that makes food • 1st Consumer – an animal that eats that plant • 2nd Consumer – an animal that eats that animal

  2. 1 10 100 1,000 The Energy Pyramid (cont.) • No energy conversion is 100% efficient • 10% rule of thumb – only about 10% of the energy passes from one level to the next • There is more energy available at the bottom of the energy pyramid (producers) then at the top (consumers)

  3. The Energy Pyramid (cont.) • Size of organisms • As you travel up the pyramid organisms get larger

  4. The Energy Pyramid (cont.) • Humans • Humans started eating lower on the food chain to deal with increasing energy needs

  5. The Energy Pyramid (cont.) • Facts • With the population increasing worldwide, humans need to do the following: • Improve agricultural techniques • Eat lower on the pyramid • Genetically modify plants (food) • IDEAS??? • It takes about 10 kg of grain to make 1 kg of beef (10% rule) HYDROPONICS

  6. The Energy Pyramid (cont.) The BIG idea: There is a lot of energy towards the bottom of the pyramid and less as you travel up.
