A bacterial population is not sustainable for infinite periods of time in a closed culture system due to nutrient depletion, lack of space, and accumulation of metabolic by-products.  Which phase shows that bacterial cells that are dying at a similar rate to bacterial growth?

A bacterium was inoculated onto three agar plates and incubated under different atmospheric conditions: in ambient air on the incubator shelf In an anaerobic jar with no oxygen In a candle jar with reduced oxygen and increased carbon dioxide After incubation, the bacterium showed moderate growth in the anaerobic jar and candle jar but heavy growth in ambient air. How should this bacterium be classified?
