Which of the following would most likely cause
an increase in the number of anaerobic bacteria
in a pond?
A. a decrease in the number of aerobic bacteria in
the pond
B. a decrease in the amount of oxygen dissolved in
the pond
C. a decrease in the temperature of the water in the
pond
D. a decrease in the amount of organic wastes in
the pond

Option B) . a decrease in the amount of oxygen dissolved in

the pond

Explanation:

Anaerobic bacteria are able to survive in the absence of oxygen while aerobic bacteria survive only in the presence of abundant oxygen.

Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.
