Unit 6: Investigating the Flow of Energy – Vocabulary Words 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Chemical energy - the potential of a chemical substance to undergo a chemical reaction to transform into other substances. Chlorophyll – the green substance (pigment) contained in the chloroplast of plant leaves that captures the energy in sunlight Chloroplast – a structure in a plant cell that contains chlorophyll, site of photosynthesis Consumer - living creatures that eat organisms from a different population. Decomposer - organism that breaks down dead organic material Decomposition – the process by which decomposers break down dead material and waste into simpler substances Energy pyramid – diagram that demonstrates the flow of energy through a food chain Food chain - the sequence of transfers of matter and energy in the form of food from organism to organism Food web - A graphical model showing the interconnecting food chains in an ecological community Glucose – a sugar molecule; product of photosynthesis Photosynthesis – process by which producers / plants use the energy in sunlight to create their own food Producer - organism on the food chain that can produce its own energy and nutrients Radiant (light) energy - energy that is transferred by electromagnetic radiation Trophic level – the position that an organism occupies in a food chain, food web, or energy pyramid (e.g., producer, primary consumer, etc.) Unit 6: Investigating the Flow of Energy – Vocabulary Words 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
