1. N2 Molecule. Nitrogen in the air is in this form

2. Nitrogen in this form can not get into a food chain

3. Nitrogen “fixed” by becoming part of an Ammonia molecule

4. Plants love Nitrogen when it is in an ammonia molecule.

6. Nitrate group NO 3

9. Nitrate fertilizer

10. Ammonium nitrate is explosive

11. Fertilizer bomb destroyed the Federal building in Oklahoma City. Killing many

12. Fertilizer plant explosion

13. Fertilizer plant explosion.. Texas. Many compounds with nitrogen in the molecule are unstable / dangerous.

15. IN ORDER TO ENTER A FOOD CHAIN… NITROGEN MUST BE IN THE FORM OF NITRATES OR AMMONIA. In other words… N2 molecules must be FIXED so the nitrogen atoms are part of NO3 or NH3 molecules

16. NITROGEN being added to the food chain as part of NH3 and NO3 molecules

17. PLANTS WILL USE THE NITROGEN IN NH3 and NO3 MOLECULES. Plants USE NITROGEN to make … protein molecules. Protein molecules have lots of Carbon atoms, Hydrogen atoms and oxygen atoms… but protein molecules must always contain NITROGEN atoms too.

28. Nitrogen fixing bacteria cells in a root nodule.

37. BOG habitat. Water leaches nitrates and ammonia out of the soil.

38. Pitcher plants in bog habitat

39. You might be in a bog if….

43. Sundew plant: Sticky

45. Stuck. Fly proteins = source of nitrogen in a nitrogen poor environment

46. Digest. Absorb the nutrients

47. Many species of sundew

48. VENUS FLY TRAP

51. More than 1 way to get nitrogen if you are a plant.

52. Pitcher Plant. Big Bog, MN

56. Big species of pitcher plant
