What are the differences between aerobic and anaerobic decay? Fill in the following table Examples of substances that form in water when organic matter is broken down: CO_2, CH_4, NH_3, NO_3, PO^3-_4, SO^2-_4 CH_3SH, HCO_3', RNH_2, H_2S (II) A lake that has a foul odor has most likely undergone A) aerobic decay B) anaerobic decay C) eutrophication D) parthenogenesis. Answer: (III) Complete the following statement regarding the type of reaction (oxidation or reduction) that occurs under aerobic and anaerobic conditions: Under aerobic conditions, microorganisms organic matter; under anaerobic conditions, microorganisms organic matter.Explanation / Answer
3.(1). In areobic decay, aerobic organism utilize considerable amount of oxygen in decomposing organic matter to realtively a stable humus under suitable environmental conditions.Oxygen from air diffuses into the moisture and it is taken up by the microbes.organic acids formed as intermediates and ,water ,CO2 are produced.
(2):In anaerobic decay does not require oxygen.organic compounds breakdown by the action of living organisms that do not require air and develope intermediate compounds including CH4, Organic acids, H2S..etc. This process is charrectarized by strong odours and present phytotoxicity.
(II), Anaerobic decay causes foul smell during the process, answer: B
(III) Aerobic decay is oxidation process in which CO2 is released, where as Anaeorobic decay is destruction of organic matter and it is reduction process.
