5. Soil with particles 0.002 -0.05 mm in diameter.






6. The result of graphing a dose-response analysis.






7. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






8. A symbiotic relationship in which one member is helped by the association and the other is harmed.






9. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






10. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.
