  1. 3. The process by which carbon dioxide and water are converted into glucose ( sugar) by plants, algae, and certain bacteria; uses sunlight energy to produce nutrients
  2. 8. Energy Resources consumed by humans much faster than nature can produce ( ex: oil, natural gas)
  3. 9. Energy Energy of moving objects, such as a rolling ball, wind or currents
  4. 13. Energy Energy of moving particles or atoms that make up all matter; heated substances have more thermal energy than cooled substances
  5. 14. Energy Energy derived from sources that are continually replenished ( wind, solar, biomass, geothermal, hydro-power)
  6. 15. Transformation One form of energy changes to another; allows energy to be used in different ways ( chemical energy in a battery transforms into electric energy in many battery-powered appliances)
  7. 16. Fossil fuel made of mostly carbonized plant matter
  8. 17. The upper layer of earth in which plants grow; provide a mixture of nutrients as well as a habitat for many organisms
  9. 18. Energy Energy of electric charges moving through conductors; powers devices used in daily life
Down
  1. 1. Gas Fossil fuel consisting of methane that occurs naturally underground
  2. 2. Fuel Nonrenewable energy source formed from remains of living organisms, which cause pollution ( coal, natural gas, petroleum)
  3. 4. Energy Energy harnessed from the sun ( radiant light and heat )
  4. 5. Energy Energy stored in atomic bonds that form molecules; released when chemical reactions occur and rearrange those atoms by breaking the bonds
  5. 6. Fossil fuel used to produce gasoline and oil
  6. 7. The process by which glucose is converted to cellular energy often with the use of oxygen
  7. 8. Energy Energy stored in the nucleus of an atom, released when protons or neutrons are added to or removed from the nucleus
  8. 10. The ability to do work
  9. 11. The act of preserving or maintaining the planet and its resources
  10. 12. Energy Energy that travels in waves ( ex; microwaves, radio waves, energy from the sun)
