Question

the process by which the food we eat is converted into energy.还原成非定语从句该怎么说呢?
It does this by slowing down metabolism,the process by which the food we eat is converted into energy.
为什么by不是放在wihich的后面?
关于by which：
（1）Here is Beijing,where I grow up.
where其实也是指代北京，不过where是在北京的意思，也就是 in Beijing
（2）Here is Beijing,in which I grow up.
其实which就是指代北京，也就是I grow up in which然后把in which提到了前面
（3）Here is Beijing,from which I come.
这句也好懂了吧，就是I come from which，which就是Beijing。
（4）Here is my car,by which I go to work.
I am waiting for the bus by which I go to school everyday
这句就是 I go to work by which，which就是car
in from by使用哪个就是根据后半句的语境来决定的
----------------------------------------------------------------
还原句子：
It does this by slowing down metabolism,（slowing down） the process by which the food we eat is converted into energy.
