Effect of Nutrient Concentration on Bacterial Growth

Easy Data Representation Interpreting Experimental Data

In an experiment, researchers studied the effect of varying concentrations of a nutrient solution on the growth of bacteria. The data collected were measured in terms of bacterial colony counts after 48 hours of exposure to the solutions. The concentrations tested were 0%, 1%, 5%, and 10%, and the results are as follows:

ConcentrationColony Count
0%50
1%120
5%200
10%180

Based on this data, what can be inferred about the relationship between nutrient concentration and bacterial growth?
