 * for the Nitrogen Cycle: **

====**1. What living organism in the soil is responsible for breaking down nitrogen and making it usable for plants to take in and grow? **====


 * The bacteria is responsible for breaking down the nitrogen and making it usable for plants to take in and grow. **

====**2. If plants can't take nitrogen in from the air, how does the nitrogen come from the air to the soil? **====

====**3. Nitrogen is a waste product, but it is an important element found in living things. What is that compound? Watch the Carbon/Nitrogen cycle movie carefully (it is found on the carbon page) **====

====**4. Why do we make sure to break down the soil and rake it in the garden rather than packing the soil down with the shovel? **==== ====The reason we break down the soil is to provide plenty of pockets of air. This oxygen in the air helps the BACTERIA iin the soil. bacteria helps the nitrogen cycle by making the nitrogen usable for plants to take in through their roots.====

**5. How much nitrogen did we find in our gardens? **
====In our gardens we found a lot of nitrogen. In some gardens there were a lot of nitrogen then in others there was none. Nitrogen is a important process in a plants life beacause it helps it grow and is as important as Air, water, and carbon.====

**6. How could we increase the amount of nitrogen in our garden soils? **
====**We could increase it by burying plants with the soil from nitriogen gardens. another option is moving the soil to the garden. We could try to break up the soil more and my last option is we could plant them by roots of trees so they give off air and nitrogen and carbon. **====
