Question

Why are more diverse populations more stable

Answer 1

I think there are a few more theories on this - but I can't quite remember them right now..

Anyway one major reason is "redundancy".

Consider two different ecosystems, one with a few species, each species has a different ecosystem function. What do you think would happen if one of those species died (perhaps a disease wipes out an entire population)?
Then think of another population that has many species so it has some have a functional overlap, what do you think would happen if you lost one species in this ecosystem?
