| energy pyramid | layered diagram showing feeding relationships and the amount of energy that is transferred within a food chain |
| Energy is being transferred. | What does the arrow on a food chain indicate? |
| the sun | the source of energy in almost all food chains |
| consumer | an organism that feeds on other organisms to obtain nourishment and energy |
| producer | Organism that manufactures its on food and therefore is the first living link in food chains and food webs |
| photosynthesis | Food-making process in producers |
| trophic level | Feeding level within a food chain/energy pyramid |
| decomposers | Fungi, bacteria, worms, and insects which break down dead or decaying matter and recycle nutrients back into the air, water, or soil |
| herbivore | 1st level consumer that eats only plants |
| carnivore | 2nd level (or higher) consumer that eats only meat |
| omnivore | consumer that eats both plants and other animals |
| tertiary (3rd level) consumer | top level consumer in a food chain or food web that has the least number of natural enemies that would feed on it |
| autotroph | synonym for producer |
| heterotroph | synonym for consumer |
| 10% | the amount of energy passed on at each level in a food chain/energy pyramid |
| Which group of living things receives the greatest amount of energy from the sun? | green plants (producers/autotrophs) |
| Which group of consumers receives the most energy in a food chain? | plant eaters (herbivores) |
| Which group of consumers receives the least amount of energy in a food chain? | tertiary or top level consumers |
| All the intertwined food chains in a given area; the transfer of the multidirectional sun's energy from producers to consumers | food web |
| the unidirectional flow of the sun's energy from producers to consumers as organisms feed on one another | food chain |
