Bacterial Growth Rates by Temperature

Very Hard Data Representation Interpreting Experimental Data

In an experiment studying the effect of temperature on the growth rate of bacteria, researchers collected data at various temperatures (10°C, 20°C, 30°C, 40°C, and 50°C). The growth rate of bacteria was measured in colony-forming units (CFUs) after 24 hours at each temperature. The data collected is summarized below:

Temperature (°C): 10, 20, 30, 40, 50

Growth Rate (CFUs): 5, 15, 45, 20, 2

Based on the data provided, which of the following statements accurately describes the growth pattern of the bacteria?

The bacteria grow optimally at 30°C, showing the highest growth rate.

Bacterial growth decreases steadily as temperature increases beyond 20°C.

There is a constant growth rate across all temperature levels.

The bacteria exhibit no growth at temperatures below 30°C.
