When most plants are initially exposed to elevated carbon dioxide levels,they will increase their rate of photosynthesis and grow more rapidly; however,some plants will drop their growth rates over time.A possible result of this phenomenon might be that plants with lower growth rates will
A) have an increased NPP.
B) be outcompeted by faster-growing species.
C) no longer play a role in the nitrogen cycle.
D) no longer require carbon.
