Across
  1. 2. A colorless, odorless gas that is formed by the combustion of carbon and organic compounds, as well as by respiration.
  2. 3. When any organic material is burned in the presence of oxygen, this occurs.
  3. 7. This process happens when inorganic nitrogen compounds are formed from nitrogen gas.
  4. 8. Water on the earth's surface penetrates the soil through this process.
  5. 10. The transformation of a liquid into a gas.
  6. 14. A nitrogen, oxygen, carbon, and water cycle belongs to this cycle.
  7. 16. The process when water from the clouds descends as rain, snow, hail, or sleet, it collects in the oceans, rivers, lakes, and streams.
  8. 17. This is a element that is inhaled by animals in order to allow aerobic respiration and survive.
  9. 19. The principal process by which bacteria convert reduced organic nitrogen (R–NH2) to reduced inorganic nitrogen (NH4+).
  10. 20. Evaporation from the land surface plus transpiration from plants represents the total evaporation.
  11. 21. This process occurs when nitrate and ammonium are taken up by soil organisms and hence become unavailable to crops.
  12. 23. Precipitation that does not make it to the soil.
  13. 27. The chemical backbone of all life on Earth is this element.
  14. 28. The process of organic matter compound degradation or oxidation into available materials to plants.
  15. 30. Nucleic acids, phospholipids, ATP, and other energy-storing molecules all contain this element.
  16. 31. The microbial process of converting nitrate and nitrite to gaseous forms of nitrogen is known as?
Down
  1. 1. The transition from a gaseous to a liquid physical state of matter.
  2. 4. The process of nitrifying bacteria convert soil ammonia into nitrates (NO3), which plants can use in their tissues.
  3. 5. When there is more water than the land can absorb, this process occurs.
  4. 6. Essential for all creatures, and its availability affects the rates at which ecosystem processes occur.
  5. 9. The process that as water flows through plants, it changes from a liquid to a gas.
  6. 11. The process by which plants and animals incorporate NO3- and ammonia produced by nitrogen fixation and nitrification..
  7. 12. The result of atmospheric water vapor condensing under the gravitational pull of clouds.
  8. 13. Phosphorus, sulfur, and trace elements are all part of this cycle.
  9. 15. This happens when animals and plants breathe in and out.
  10. 18. A harmful algal bloom is referred to as this term.
  11. 22. This process allows Nitrogen to be transformed into different chemical forms as it travels through the atmosphere, terrestrial, and marine ecosystems in a biogeochemical cycle.
  12. 24. This is the conversion of light energy into chemical energy by plants and other organisms.
  13. 25. A system that helps oxygen migrate through the Earth's three primary regions: the atmosphere, biosphere, and lithosphere.
  14. 26. It is a vital component of proteins and nucleic acids, and it is required for life on Earth.
  15. 29. The process by which groundwater departs the ground is known as?
