Across
  1. 5. - The breakdown of non-living matter, releasing carbon dioxide and decaying matter (13)
  2. 6. - A chemical reaction that releases carbon dioxide into the atmosphere by burning fossil fuels (10)
  3. 8. - A group of microorganisms that take nitrogen from the air and use it to form nitrates (8,6)
  4. 9. - The cooling of water vapour in the atmosphere, resulting in rainfall (13)
  5. 10. - A reaction that releases energy from carbon-containing compounds, as well as carbon dioxide into the atmosphere (11)
  6. 11. - A process that removes atmospheric carbon from the air, using it to make food (14)
Down
  1. 1. - A process that takes millions of years, turning dead matter in fossil fuels (13)
  2. 2. - The loss of water from plants as water vapour, released into the atmosphere (13)
  3. 3. - A group of bacteria that breakdown nitrates in the soil and release atmospheric nitrogen (12)
  4. 4. - A nitrogen-containing compound that is released from decomposers as they breakdown dead matter. Also found in urine (7)
  5. 7. - A process where water trickles through gaps in rocks and soil, eventually reaching the ocean (11)
