Energy Flow

2. a system of interlocking and interdependent food chains.
4. An animal that eats both plants and animals.
7. A consumer that eats only plants.
12. represents the total mass of living organic matter at each trophic level
13. this is an organism that only eats meat and is a carnivore
16. represents the energy available at each trophic level; levels ALWAYS get smaller as you go up the pyramid (Remember the Rule of 10!).
17. A consumer that eats only animals.
19. Also called heterotrophs get energy from living or once-living organisms.
20. Where does all energy come from?

1. a consumer that is at the top of a food chain/web and is considered to be the "alpha".
3. organism that eats dead organic matter. Also known as detritivores.
5. the levels of nourishment in a food chain.
6. represents the number of organisms at each trophic level.
8. models that show how energy flows through an ecosystem.
9. A series of steps in which organisms transfer energy by eating and being eaten.
10. a process in which oxygen is converted to carbon dioxide and carbon dioxide then being converted into oxygen
11. Also called autotrophs get energy from nonlivingsources Most capture energy during photosynthesis to make simple sugars.
14. the flow of energy through living things within an ecosystem.
15. herbivores, carnivores, omnivores, detritivores/decomposers.
18. this is an organism that produces its own energy and obtains this through photosynthesis
