• turkey legs

• broccoli flowers

• raspberries

• swordfish

Amelia claims that when the outside air temperature gets too hot, the rate of photosynthesis in a plant decreases. Amelia conducts an experiment to support her claim.Amelia exposes five bean plants to different air temperatures for 24 hours. Then, she measures the amount of glucose made by each plant. The table shows the data from her experiment.

The conclusion that is best supported by the evidence is: As the GROWTH TEMPERATURE INCREASES the ____________.

• temperature decreases

• amount of glucose increases

• amount of glucose decreases

• type of plant changes
