There would be a lot of herbivores. Also their would be a lack of vegetation eventually in their area because the secondary consumers will not eat most of the primary consumers like deer and squirrels which in turn will eat all of the vegetation. This would conclude that the herbivores would eventually die do to starvation, that is why the meat eaters are needed in a ecosystem.
Hope this helps just took this quiz today and got a 4/4 on my answer so hopefully this will help you guys.
