Final answer:
A bar graph is a useful tool for comparing data in different categories. In this case, the graph represents the growth of plants with and without worms. The bars for plants without worms should be higher than the bars for plants with worms, indicating that plants without worms grew taller.
Step-by-step explanation:
A bar graph is a useful tool for comparing data in different categories. It consists of horizontal or vertical bars that represent the values in each category. In this case, the graph to the right represents the growth of plants with and without worms. The vertical axis represents the frequency or number of plants, and the bars represent the growth of plants with and without worms. The bars for plants without worms should be higher than the bars for plants with worms, indicating that plants without worms grew taller.
