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