Line graph would be useful to show the growth rate of plants at varying temperatures.
Answer: Option C
Explanation:
Graphing are an important process in which scientists view data collected in a controlled experiment. The type of graph most commonly used in biology is a line graph. They are used to track changes in the short and long term periods.
For smaller changes, it is better to use line graphs than bar charts. It can also be supported to compare variations in more than a group in the same period. The commonly used line graphs are linear, polynomial, power, rational, quadratic, sinusoidal, logarithmic and exponential.
