Whereby

Could you please tell me the usage of "whereby"?

Mechanisms develop whereby every successful species can
_____ its innate capacity for population growth with the constraints that arise through its interactions with the natural environment.
A. enhance
B. replace
C. produce
D. surpass
E. reconcile

Is the boldfaced "phrase" grammatically wrong? I see two main verbs there.

Your help would be highly appreciated.

Thank you so much! Emotion: smile So it can be used as a relative pronoun.

So in that sentence, "mechanisms" is a subject, "develop" i

Hello Jeff

You can think of it like this:

'Mechanisms – by which every successful species can reconcile its innate etc. – develop..."

So the 'which' relates to 'mechanisms'.
