Question

If all the plants steps performing photosynthetic process. What will happen?

Answer 1

With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days.

Then the animals that temporarily relied on them for sustenance would die
