Across
- 2. In ecology, this refers to populations of various species that are co-occurring at the same time and place
- 6. The shared beliefs, values, and knowledge of a defined group of people
- 7. Atmospheric gases that efficiently absorb infrared radiation and then dissipate some of the thermal energy gain by re-radiation
- 11. The place or “home” where a plant or animal lives, including the specific environmental factors required for its survival
- 14. The physical process by which infrared-absorbing gases (such as CO2) in Earth’s atmosphere help to keep the planet warm
- 17. of or relating to or characteristic of conditions in the subtropics
- 18. An increasing concentration of hydrogen ions (H+) in soil or water.
- 20. The prevailing, long-term, meteorological conditions of a place or region, including temperature, precipitation, wind speed, and other factors. Compare with weather
- 21. A permanent conversion of forest into some other kind of ecosystem, such as agriculture or urbanized land use
- 22. major ecological community with distinct climate and flora
- 25. The abundance of a species that can be sustained without the habitat becoming degraded
- 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
- 27. a fluorocarbon with chlorine
- 29. A biological interaction occurring when the demand for an ecological resource exceeds its limited supply, causing organisms to interfere with each other
Down
- 1. This occurs when species interact in ways that affect their reciprocal survival, and so are subject to a regime of natural selection that reinforces their mutual evolutionary change
- 2. An animal that hunts and eats other animals
- 3. The breakdown of organic molecules into simpler compounds through the metabolic actions of microorganisms
- 4. An event of high phytoplankton biomass.
- 5. regions adjacent to the tropics
- 8. A general term used to describe one or more communities that are interacting with their environment as a defined unit. Ecosystems range from small units occurring in microhabitats, to larger units such as landscapes and seascapes, and even the biosphere
- 9. Groundwater resources in some defined area
- 10. A temperate or tropical biome characterized by prolonged drought, usually receiving less than 25 cm of precipitation per year
- 12. Heat in Earth’s crust, which can sometimes be used to provide energy for heating or generation of electricity
- 13. The biochemical deoxyribonucleic acid, the main constituent of the chromosomes of eukaryotic organisms
- 15. A model of the trophic structure of an ecosystem, organized with plant productivity on the bottom, that of herbivores above, and carnivores above the herbivores
- 16. The proportional contribution of an individual to the progeny of its population
- 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
- 23. A hierarchical model of feeding relationships among species in an ecosystem
- 24. A geographically extensive ecosystem, occurring throughout the world wherever environmental conditions are suitable
- 28. A complex model of feeding relationships, describing the connections among all food chains within an ecosystem
