Two identical trays each containing 50 grams of sunflower seeds are placed in a cool dry location. Nothing else is added to the control tray, but the experimental tray receives a mating pair of grain weevils. After 2 weeks, the control tray looks essentially the same, but the experimental tray is now crawling with thousands of weevils actively consuming the seeds. You can see that no weevils have left the tray, and that all of their waste (frass) has fallen in the tray. Based on your understanding of the transformation of energy and matter, which of the following predictions about the relative weights of the two trays is most likely correct? Select one: a. The experimental tray will weigh less than the control tray because the weevils are releasing mass in the form of CO2 gas through cellular respiration b. The control tray will weigh less than the experimental tray because the seeds in it have been undergoing cellular respiration c. The control tray will weigh more than the experimental tray because the uneaten seeds will undergo photosynthesis. d. The experimental tray will weigh more than the control tray because of the added weight of all the weevils

Question

Two identical trays each containing 50 grams of sunflower seeds are placed in a cool dry location. Nothing else is added to the control tray, but the experimental tray receives a mating pair of grain weevils. After 2 weeks, the control tray looks essentially the same, but the experimental tray is now crawling with thousands of weevils actively consuming the seeds. You can see that no weevils have left the tray, and that all of their waste (frass) has fallen in the tray. Based on your understanding of the transformation of energy and matter, which of the following predictions about the relative weights of the two trays is most likely correct?

Select one:
a. The experimental tray will weigh less than the control tray because the weevils are releasing mass in the form of CO2 gas through cellular respiration
b. The control tray will weigh less than the experimental tray because the seeds in it have been undergoing cellular respiration
c. The control tray will weigh more than the experimental tray because the uneaten seeds will undergo photosynthesis.
d. The experimental tray will weigh more than the control tray because of the added weight of all the weevils.
