I freely admit the 'Nature is wise" concept is good and vaild.
But then they segue right into "One of the most important classes of compounds that result from decomposition are the nitrogen-based substances, and the process through which they are gradually transformed is called the Nitrogen Cycle." Beep! Wrong! The Nitrogen Cycle is a great deal more than decomposition of nitrogenous compounds.
Follow that up with " How and who makes these transformations? They are microscopic beings called nitrifying bacteria, whose role in nature is that of decomposers of nitrogen compounds." Beep! Wrong again! Nitrifying bacteria in our language are those resonsible for oxidation of the breakdown products from nitrogenous compounds. The ones doing the breakdown are the heterotrophic bacteria, the saphrophytes (bacteria or fungi) and the inhabitants themselves (micro and macro).
This analysis could continue throught just about every topic sentence in the article, not even counting spelling errors, out-of-date nomenclature, etc.
It was a nice effort, ruined because they did not get review by anyone who knew.
