Across
- 1. soil made with a balance of the three main types of soil: sand, silt, and clay
- 4. sediment whose particles are larger than silt
- 5. a microbial process by which reduced nitrogen compounds are sequentially oxidized to nitrite and nitrate
- 6. sediment with particles smaller than silt
- 8. the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere
Down
- 2. When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen
- 3. the process by which plants and animals incorporate the NO3- and ammonia formed through nitrogen fixation and nitrification
- 7. sediment whose particles are between clay and sand in size
