Expert Solution
Step 1

Bacteria grow rapidly under a favorable environment where all the necessary conditions for its growth are present. When bacteria are grown in a closed system or batch culture where neither the food is added nor the waste is removed, bacteria grow in a predictable pattern and when it is plotted on a graph, a distinct curve known as bacterial growth curve is obtained.
