A month-long study of plant growth was conducted. Three groups of plants were grown in various amounts of light: Group A received 12 hours of light per day. Groups B & C received 8 and 4 hours of light, respectively. The average rate of growth of each group is graphed here. How does the data support the idea that ALL living things have certain basic needs in common?
Responses
AOver time, all three groups grew. Since they all received light, the limiting factor must have been water. Water is also required for photosynthesis.

BPlant growth was greatest in the group that received the most light. As in all living things, the amount of light correlates to the amount of growth.

CPlant growth was greatest in the group that received the most light. We can infer that growth was supported by photosynthesis which in turn provided food to the plants. Food is a basic need of all living things.

DPlant growth was greatest in the group that received the most light. We can infer that growth was supported by photosynthesis, which requires carbon dioxide. We can infer, then, that all living things required carbon dioxide for adequate growth.
