  1. 2. In ecology, this refers to populations of various species that are co-occurring at the same time and place
  2. 6. The shared beliefs, values, and knowledge of a defined group of people
  3. 7. Atmospheric gases that efficiently absorb infrared radiation and then dissipate some of the thermal energy gain by re-radiation
  4. 11. The place or “home” where a plant or animal lives, including the specific environmental factors required for its survival
  5. 14. The physical process by which infrared-absorbing gases (such as CO2) in Earth’s atmosphere help to keep the planet warm
  6. 17. of or relating to or characteristic of conditions in the subtropics
  7. 18. An increasing concentration of hydrogen ions (H+) in soil or water.
  8. 20. The prevailing, long-term, meteorological conditions of a place or region, including temperature, precipitation, wind speed, and other factors. Compare with weather
  9. 21. A permanent conversion of forest into some other kind of ecosystem, such as agriculture or urbanized land use
  10. 22. major ecological community with distinct climate and flora
  11. 25. The abundance of a species that can be sustained without the habitat becoming degraded
  12. 26. A symbiosis in which one of the species benefits from the interaction, while the other is not affected in either a positive or negative way
  13. 27. a fluorocarbon with chlorine

  12. 16. The proportional contribution of an individual to the progeny of its population
  13. 19. An organism that synthesizes its biochemical constituents using simple inorganic compounds and an external source of energy to drive the process. See also primary producer, photoautotroph, and chemoautotroph
