Unit 3 NitrogenCycle
BMMS Unit 3 Nitrogen Cycle
| Question | Answer |
|---|---|
| Nitrogen Cycle Components | Atmosphere Nitrogen Gas Lightning Nitric Acid Roots Nitrogen-fixing bacteria Soil Nitrogen Decomposing Consumption by Animals Consumption by Plants |
| Nitrogen Cycle 1 | This element is necessary to make proteins which are needed for many of the process and material of life |
| Nitrogen Cycle 2 | The ______ cycle allows this element to change forms and be utilized by organisms found on planet Earth |
| Nitrogen Cycle 3 | Most of this element (78%)is found on Earth is contained in the atmosphere, however, bacteria in the soil is vital in allowing nitrogen to be usable for other organisms, including plants and animals |
| Nitrogen Cycle- Atmosphere Nitrogen Gas | 78% of the nitrogen found on Earth is in the atmosphere |
| Nitrogen Cycle- Lightning Nitric Acid | Lightning is one mechanism that can change nitrogen into a usable form |
| Nitrogen Cycle- Roots Nitrogen-fixing bacteria | Bacteria found on roots of legumes can fix nitrogen into a usable form |
| Nitrogen Cycle- Soil | Other bacteria can convert fixed nitrogen into nitrates and nitrites for plants |
| Nitrogen Cycle- Nitrogen Decomposing | When animals decompose, nitrogen is put back in the soil |
| Nitrogen Cycle- Consumption by Animals | Animals eat plants that contain nitrogen |
| Nitrogen Cycle- Consumption by Plants | Plants get usable nitrogen from bacteria in the soil |
