- 5. movement of molecules or particles from an area with higher concentration to lower concentration
- 7. living things breathe this in
- 8. protects the cell from other things around it
- 10. a movement of substances across a cell membrane without the use of energy
- 11. radiation from the sun is getting absorbed by greenhouse gases and aren't reflecting back into space
- 12. the process of phosphorous moving through the lithosphere, hydrosphere, and biosphere
- 15. a cellular transportation where substances move against a concentration gradient and requires energy
- 16. living things breathe this out
- 17. the concentration inside the cell is higher than the concentration of outside the cell
- 18. a shift in global weather patterns
