Across
  1. 3. the one thing a scientist manipulates or tests on purpose during an experiment
  2. 4. a monosaccharide sugar that is produced in photosynthesis and used during cellular respiration for energy production
  3. 6. a gas released by plants during photosynthesis; used during cellular respiration
  4. 7. the cumulative body acquired of observation or experimentation in which scientific explanation is based
  5. 13. mass is neither created nor destroyed in ordinary chemical and physical changes
  6. 16. ingredient in a chemical reaction
  7. 17. support proper function and growth
  8. 19. a chemical reaction during which plants convert radiant energy from the Sun to chemical energy; the reaction converts carbon dioxide and water into sugar (glucose) and oxygen
  9. 22. organisms that produce their own food. Also known as producers.
  10. 23. a representation or description designed to make a particular part/feature of the world easier to understand
  11. 26. carbon dioxide dissolving in the oceans
  12. 27. the structure in a cell where cellular respiration takes place
  13. 29. the structures within plant cells where photosynthesis takes place
  14. 30. the results that are measured/observed during an experiment
Down
  1. 1. continuous loops, moving between living organisms (producers, consumers, decomposers) and the nonliving environment (air, water, soil) through processes like photosynthesis, respiration, respiration and decomposition!
  2. 2. energy cannot be created or destroyed, only transformed from one form into another
  3. 5. the process of obtaining energy from the breaking of chemical bonds in nutrients; ALL cells do this
  4. 8. the burning of fossil fuels or other materials
  5. 9. anything that has mass and takes up space
  6. 10. what is made in a chemical reaction
  7. 11. air/gas above the surface of Earth)
  8. 12. the cycling of carbon throughout Earth's spheres
  9. 14. anything that absorbs more carbon from the atmosphere than it releases
  10. 15. usable energy in all living cells
  11. 18. organisms that obtain energy by eating other organisms. Also known as consumers.
  12. 20. the ability to do work or cause change.
  13. 21. the breakdown of plant and animal matter by decomposers to return nutrients to the soil
  14. 24. non-renewable resources that release carbon into the atmosphere when burned
  15. 25. a gas released during cellular respiration; used by plants during photosynthesis
  16. 26. main pigment found in the chloroplasts of plants
  17. 28. factors during an experiment that are controlled so that they don't affect the dependent variable
