Flow of Energy

5. - Overlapping food chains with different pathways to show the flow of energy in an ecosystem,
6. - An organism that transforms energy from the Sun and uses carbon dioxide and water to make food,
8. - the green substance (pigment) contained in the chloroplast of plant leaves that captures the energy in sunlight,
9. - A self-contained living thing,
11. - the process by which decomposers break down dead material and waste into simpler substances,
14. - A collection of organs that work together to perform specialized functions,
16. - A single, linear path showing the flow of energy from the Sun to a producer and through different levels of consumers,
17. - A collection of similar tissues joined together into a structure that performs specialized functions,
18. - A mass of similar cells that perform a specialized function, Transform - make a thorough or dramatic change in the form, appearance, or character of,

1. - A sugar composed of six carbon atoms that is the preferred energy source for most cells; produced by photosynthesis,
2. - The position an organism occupies on the food web
3. - a structure in a plant cell that contains chlorophyll; site of photosynthesis,
4. - Organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion,
7. pyramid - A diagram that shows the total amount of energy contained within each trophic level,
10. - An organism that must consume other organisms for nutrients,
