Across
  1. 3. obtains most of its body heat from its surroundings
  2. 8. when water becomes too high in nutrients from runoff and causes algae blooms
  3. 13. generates heat internally
  4. 15. higher concentration of solutes on the outside of a barrier
  5. 16. nonliving
  6. 17. does not require oxygen
  7. 18. movement of water across a semipermeable barrier in response to differences in solute concentration on either side

Down
  1. 1. all of the organic and inorganic materials that an organism needs to metabolize, grow, and reproduce
  2. 2. lower concentration of solutes on the outside of a barrier
  3. 4. internal balance of physical factors that keeps organisms alive
  4. 5. this type of waste is produced in all organisms and must be removed from cells
  5. 6. Living portion of an organism’s environment
  6. 7. requires oxygen
