[edit] Nitrogen cycle figure
I believe the image is from the site of the book; Campbell and Reece: Biology. You'll need a accescode for the site; www.campbellbiology.com
- Is this statement meant to dispute the basis for the USEPA employee authorship and public domain status of the graphic in the article? So far, I'm not buying it: image looks to be PD. -- Paleorthid 20:36, 18 June 2006 (UTC)
I don't really understand what you're trying to say. I've checked my book, and the image is indeed in it. Don't believe me? Check it out for yourselve: Campbell & Reece, Biology. I have the seventh edition, and there the image appears on page 1197. And hey, I'm only trying to help.
- The image appears on the EPA's website [1]. I don't see anything that suggests they lifted it anywhere else (or, if they did, they're doing so illicitly), so it seems PD to me. Could it be that Campbell and Reece have "borrowed" it? Cheers, --Plumbago 11:17, 20 June 2006 (UTC)
[edit] Sources of oxygen
Are we sure that the oxygen atom in the NO2 -> NO3 step comes from water? The Nitrifying_bacteria pages lists otherwise. 216.59.231.35 16:41, 10 November 2006 (UTC)
