Across
- 3. It is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere.
- 5. energy obtained from the sun's radiation
- 7. The circulation or cyclic movement of nitrogen from the atmosphere to soil and back into the atmosphere.
- 12. combining of two small atoms such as Hydrogen or Helium to produce heavier atoms and energy
- 13. it is a process by which nitrogen (N2) in the Earth's atmosphere is converted into ammonia (NH3)
- 14. it is a form of renewable energy produced through machines that use wind as their power source.
- 17. it is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate.
- 18. it is thermal energy generated and stored in the Earth
Down
- 1. transport of energy by ocean surface waves and capture of that energy
- 2. it is the conversion of nitrates (NO3) to inert nitrogen gas (N2).
- 4. energy that comes from resources which are naturally replenished on a human.
- 6. It is the is the converting of energy coming from running water to produce electricity
- 8. energy released by reactions within atomic nuclei, as in nuclear fission or fusion.
- 9. it is the process by which the organically bound nitrogen of microbial,plant and animal biomass is recycled after their death
- 10. is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms
- 11. is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compounds present in the environment
- 15. capacity to do work by mechanical,physical,chemical or electrical tasks or to cause a heat transfer between two
- 16. it is the any kind of energy that uses a biological organism (plant or animal) as its source.
