Storyboard Text

  • "Harambe & Keaton"
  • Fixation, Ammonification, Nitrification, Assimilation.
  • Dentrification.
  • Keaton: What are you eating, Harambe? Harambe: Just some plants. Keaton: Actually, did you know you're eating Nitrogen? Harambe: What? No way.
  • Keaton: Yeah actually. Special bacteria of plants takes in nitrogen. As they do that, they receive carbohydrates. So then the Nitrogen goes back into the dirt. Bacteria in the dirt uses enzymes to change the nitrogen to ammonium ions. Plants can also take in nitrogen from the few nitrate ions in the soil by their roots. This is called Assimilation.
  • Keaton: There are also some soil bacteria that can convert the nitrates in the earth back into nitrogen to send back to the atmosphere. Harambe: That's cool...but how am I eating nitrogen. Keaton: Well, when animals like us eat plants we eat the nitrogen in them also.
