In regards to eating meat

[BrownEye]

Some plants have some pretty obvious defense mechanisms.

For instance, a healthy and natural kale plant will grow thick little hairs on both the stems and leaves. This is to prevent bugs from eating it.

Is this a natural method of selection? Say to allow for the chance of a mammal to eat, rather than the insects? It may be that the natural habitat would allow for the insects to get their sustenance from all the neighboring plants, while keeping an extra level of defense in order to keep sustenance available for another species that coexists in the same area. The word Flourish comes to mind.

I would assume that it would be hard for species overlap if everything was eaten by insects. While at the same time, if the insect predators are eliminated the insects would be able to overpopulate and eat everything, including all mammals/us.
