An established bacterial community is exposed to a dark environment for several days. Bacteria that require light to reproduce will show _________ compared to bacteria that do not require light to reproduce. (1 point)
Responses
the same amount of growth
the same amount of growth
lack of growth
lack of growth
uncontrollable growth
uncontrollable growth
more growth
lack of growth
The correct answer is "lack of growth."
Explanation:
Bacteria that require light to reproduce are known as phototrophic bacteria. They use light energy to carry out photosynthesis, which is essential for their growth and reproduction. When these bacteria are exposed to a dark environment for several days, they will lack the necessary light energy to carry out photosynthesis. As a result, they will not be able to reproduce and show a lack of growth compared to bacteria that do not depend on light for reproduction.
