In order to determine the impact of a dark environment on bacterial growth, we need to understand the role of light in bacterial reproduction. Light is an essential factor for the growth of bacteria that undergo photosynthesis to reproduce. These photosynthetic bacteria use light energy to convert carbon dioxide into organic matter, which fuels their growth.
If an established bacterial community, which includes photosynthetic bacteria, is exposed to a dark environment for several days, we can expect that bacteria requiring light for reproduction will show a lack of growth compared to bacteria that do not rely on light for reproduction.
This is because without light, photosynthetic bacteria cannot carry out photosynthesis and produce the necessary organic matter for their growth. On the other hand, bacteria that do not require light for reproduction can still obtain energy and nutrients through other metabolic processes such as fermentation or respiration, allowing them to continue growing even in the absence of light.
Therefore, the correct answer to the question is "lack of growth" for bacteria that require light to reproduce, while bacteria that do not require light may still show the same amount of growth or potentially more growth in the dark environment.
