What would happen if Herbivores disappeared?
(assuming omnivores are now carnivores)
Life on Earth would eventually cease to exist.
Why? All energy comes from the sun, no herbivores means that there are no animals eating plants & animals can't take energy from the sun, only plants. Eventually Animals would have to eat heaps of food for just one meal because you get only half of the energy from the animal you eat. After a while, all animals would die, and plants would eventually use up all the carbon dioxide with no animals to produce more.
