In Lab,you Are Studying the Long Term Effects of Elevated

In lab,you are studying the long term effects of elevated carbon dioxide levels on photosynthesis in C3 and C4 plants.The C3 and C4 plants are growing in separate closed chambers.Both chambers are constantly given elevated but equal amounts of carbon dioixde.Which of the following are likely results of this experiment? Check all that apply.

A) There would be a decrease in O₂ levels in both chambers.
B) There would be an increase in O₂ levels in both containers.
C) Both the C3 and the C4 plants would show equal gains in biomass.
D) The C4 plants would gain more biomass relative to the C3 plants.
E) The C3 plants would gain more biomass relative to the C4 plants.
