Across
  1. 4. A chemical process in which oxygen is used to make energy from carbohydrates (sugars).
  2. 8. The continuous movement of water within the Earth and atmosphere.
  3. 9. A biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to the organism and back into the atmosphere.
  4. 12. A type of cellular transport in which substances (e.g. ions, glucose, and amino acids).
  5. 13. The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
  6. 15. The process by which cells derive energy from glucose.
  7. 20. The membrane found in all cells that separates the interior of the cell from the outside environment.
Down
  1. 1. The biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
  2. 2. Nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
  3. 3. A type of membrane transport that does not require energy to move substances across cell membranes.
  4. 5. The type of respiration through which cells can break down sugars to generate energy in the absence of oxygen.
  5. 6. The movement of matter between the Earth, the atmosphere, and living things.
  6. 7. A chemical element with an atomic number of 8 (it has eight protons in its nucleus).
  7. 10. Long-term shifts in temperatures and weather patterns, mainly caused by human activities, especially the burning of fossil fuels.
  8. 11. The movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.
  9. 14. A 6-carbon structure with the chemical formula C6H12O6.
  10. 16. The source of energy for use and storage at the cellular level.
  11. 17. Any external solution that has the same solute concentration and water concentration compared to body fluids.
  12. 18. A chemical compound with the chemical formula CO2
  13. 19. The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
