Mam.....I want to ask that......if microbes can survive extreme temperature.....then how can refrigdation help in preventing food spoilage???

[@hashimabdulaziz4677]

I think it slows down the microorganism from spoiling the food and when freezing it will also freeze the microorganism even in nature we can find like in sout poles of earth the organisms are actually frozen but if it melt it will be active again. Hope it help

[@ree_done-_-]

Why does the bacteria again converts the nitrogen into gaseous form in the last step ?

[@anwitadwivedi2924]

So that the nitrogen that is now in the soil should get back to the atmosphere as if the nitrogen gets stored in the soil and the bacteria doesn't converts it in atmospheric N2 then their would be a lack of nitrogen in the atmosphere.remember what is the taken needs to be returned back to it to maintain the ecological balance.
