Across
  1. 6. Organisms that are in higher trophic levels eat more poisons which accumulate in their bodies
  2. 7. Water vapor cooling and forming liquid
  3. 8. Organisms that can produce the energy they need from sunlight
  4. 10. These eat dead producers and consumers and are considered heterotrophs
  5. 12. These eat producers or other consumers and are considered heterotrophs
  6. 15. converting nitrogen into more useful forms or putting it back into the air
