Plants are more efficient at acquiring carbon than are fungi,in the form of carbon dioxide,and converting it to energy-rich surgars.
这道题的正确选项是C 为：
Plants are more efficient than fungi at acquiring carbon
不明白为什么，比较的时候不是不能省略助动词或动词吗？因此做题的时候下意识的就选了有are的A选项，不知道为什么错了，请高手指点。。

A) there is nothing that parallels the non-underlined phrase "and converting it to energy-rich surgars."
Look at the simplified correct sentence C), Plants are more efficient than fungi at acquiring carbon and [at] converting it to energy-rich surgars.

似乎有点明白2楼的意思了，但是这个are难道就不该加吗？到底在什么情况下 这个are可以省略啊 C选项如果在fungi前面加上are 还对吗

are可有可无，因为如果省略也不产生歧义。这题考点是and前后平行
