Across
  1. 1. the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere.
  2. 3. the rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gasses released by people burning fossil fuels.
  3. 4. the cycle of the continuous movement of water within the Earth and atmosphere.
  4. 6. powers nearly all forms of cellular work.
  5. 7. the Earth’s surface heat getting trapped in the atmosphere from greenhouse gasses.
  6. 8. that have less solute present.
  7. 13. when particles move from high concentration to low concentration.
  8. 14. significant changes in global temperature, precipitation, wind patterns and other measures of climate that occur over several decades or longer.
  9. 16. when organisms take in sunlight as a form of energy and convert it into sugars.
  10. 17. the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
  11. 19. the membrane found in all cells that separates the interior of the cell from the outside environment.
  12. 20. that have equal concentrations of substances.
  13. 22. that have more solute present.
  14. 24. a cycle where nitrogen goes through the atmosphere then cycles through to the ground into the roots of plants.
  15. 25. a process which takes place in the absence of oxygen gas.
Down
  1. 2. when organisms take in food and use the chemical energy they obtain from sugars.
  2. 5. a chemical process in which oxygen is used to make energy from carbohydrates.
  3. 9. movement of materials through a membrane against concentration gradient and requires energy from the cell.
  4. 10. the part of a system in which some portion of the system's output is used as input for future operations.
  5. 11. occurs when a cell uses no energy to move particles across a membrane.
  6. 12. the total amount of greenhouse gasses produced to directly and indirectly support human activity.
  7. 15. the main type of sugar in the blood and is the major source of energy for the body's cells.
  8. 18. a gas absorbed from the air by plants in photosynthesis and exhaled by humans.
  9. 21. the diffusion of water across a selectively permeable membrane.
  10. 23. a gas inhaled by humans and put out by plants through cellular respiration.
