Bacteria that require light to reproduce will show a lack of growth compared to bacteria that do not require light to reproduce.

To understand why, we need to consider the role of light in photosynthesis. Some bacteria, like photoautotrophic bacteria, use light energy to produce organic compounds through photosynthesis. This process is essential for their growth and reproduction. However, in a dark environment, these bacteria are unable to carry out photosynthesis and, as a result, cannot produce the necessary energy to support their growth and reproduction. Therefore, their growth will be inhibited, leading to a lack of growth.

On the other hand, bacteria that do not rely on light for reproduction, such as heterotrophic bacteria, can obtain energy from other sources, such as organic matter. These bacteria are not affected by the absence of light and can continue to grow and reproduce.

So, when an established bacterial community is exposed to a dark environment for several days, the bacteria that require light to reproduce will show a lack of growth compared to bacteria that do not require light to reproduce.
