Consumers/ Heterotrophs Herbivore Omnivore Plant eater Carnivore Plant and meat eater Meat eater Producer/ Autotroph Makes own food Food Chain Vocab Breaks down dead organisms Has to eat to get energy Eats already dead animals (road kill) Decomposer Consumer/ Heterotroph Scavenger
Notice the arrow direction!! A food chain shows the path of energy from one living thing to another. The arrows show the direction of energy not who's eating who.
So the bird is eating the butterfly. The energy is flowing to the bird.
(Photosynthesis) Radiant energy is converted to chemical energy and passed on to other organisms in the ecosystem. Energy passes from Sun to Producers to consumers
$10 Only 10% of the energy is passed on. Some energy is used and some is lost as heat. $10,000 http://www.cambridgema.gov/TheWorks/departments/recycle/images/grass.jpg http://www.vdh.state.va.us/epidemiology/DEE/Vectorborne/WestNile/images/Hawkrt.jpg $1000 $100 http://www.idratherbewriting.com/wp-content/uploads/2007/07/grasshopper.jpg http://www.australianfauna.com/images/pilligamouse.jpg

Chains can also be arranged in an energy pyramid. Producers are on the bottom because they have the most energy http://www.westone.wa.gov.au/k-12lrcd/learning_areas/geography/geog2B/content/cell4_spatial_impact/images/se751_idea04_pic04.gif
Least mass Least Energy 3rd to eat Tertiary Consumer 2nd to eat Secondary Consumer First to eat Primary Consumer Most energy Most mass Producer

Removing an organism from the chain or pyramid will cause great harm and the closer it is to the beginning or bottom the worse it is.
