Across
  1. 9. The global sum of all ecosystems, including all life forms and their interactions with the Earth’s atmosphere, hydrosphere, and lithosphere.
  2. 11. management The practice of managing natural resources and ecosystems in a sustainable way that meets ecological, economic, and social needs.
  3. 13. A unit of measurement used to describe the concentration of substances in water, particularly in the context of salinity.
  4. 14. The microbial process of converting nitrates into nitrogen gas, releasing it back into the atmosphere.
  5. 15. Any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.
  6. 17. Zone The twilight zone of the ocean, receiving minimal sunlight, located below the epipelagic zone.
  7. 18. The process by which microorganisms decompose organic matter, converting it into ammonia.
  8. 19. The ability to maintain ecological processes, biodiversity, and productivity over time.
  9. 20. The process by which water vapor in the air cools and changes into liquid water droplets.
Down
  1. 1. The layer of gases surrounding the Earth, essential for life by providing oxygen, carbon dioxide, and other critical elements.
  2. 2. The process by which water is absorbed by plant roots, moves through plants, and is released as water vapor from leaf pores.
  3. 3. The process by which water changes from a liquid to a gas or vapor.
  4. 4. species The first organisms to colonize a barren or disturbed ecosystem, initiating ecological succession.
  5. 5. The process by which plants and animals incorporate nutrients, such as nitrogen, into their tissues.
  6. 6. The process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide and water.
  7. 7. The combined process of water evaporation from the Earth's surface and transpiration from plants.
  8. 8. All the water on Earth, including oceans, lakes, rivers, groundwater, and ice.
  9. 10. Zone The upper layer of the ocean where sunlight penetrates, also known as the sunlight zone.
  10. 12. Large ecological areas with distinct climate, plants, and animals, such as deserts, forests, and tundras.
  11. 16. community A stable and mature community that has reached the final stage of ecological succession.
