Nitrogen Cycle Lesson PowerPoint, Environment, Ecosystem, Biogeochemical Cycles

  1. 1. • All life requires nitrogen-compounds, e.g., proteins and nucleic acids. • Air, which is 79% nitrogen gas (N2), is the major reservoir of nitrogen. • But most organisms cannot use nitrogen in this form. • Plants must secure their nitrogen in "fixed" form, i.e., incorporated in compounds such as: – nitrate ions (NO3−) – ammonia (NH3) – urea (NH2)2CO • Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants).

Chutes and Ladders, the Nitrogen Fixation game. • Link to Chutes and Ladders (Nitrogen Cycle Game) – Please play chutes and ladders the nitrogen fixation game until the end of class. – Record your journey until you reach crop uptake in your journal…..then just play. – Must make whoooop or weeee sound down chute. – If you go off the board go back to start. – If someone lands on you, your denitrified-go back to start.
