Unit 3 Nutrient Cycles

5. Happens in multiple cycles, the over addition of nutrients in bodies of water causing a large algae growth.
6. Nutrients taken by water from the 3 other cycles to bodies of water.
9. A phase of water where it turns from a liquid to a gas due to sun rays.
12. Water from clouds redistributing as different forms of cold or hot liquid.
14. A limiting factor in ecosystems, is in 80% of air.
15. Stores carbon for a long time due to its long lifespan.
16. Ammonium is converted into nitrites and nitrates by bacteria.
17. Plants absorb the nitrites and ammonium.

1. Water stored to be put back into the water cycle again.
2. They are able to fix nitrogen in order for organisms to grow more easily.
3. A limiting factor in all ecosystems, doesn't have an atmospheric form.
4. Bacteria converts a small percentage of nitrates back into the air.
7. A phase of water where it turns from a gas to a liquid that creates clouds.
8. Contain one of the cycles, allowing it to get into water more easily.
10. Bacteria converts nitrogen into ammonium and ammonia.
11. The cycle that allows for the material to be reused over and over in different phases.
13. An energy molecule that consists mainly as a gas, but can be transferred through multiple materials.
