If the number of carnivores increases, the omnivores will decrease in number as carnivores are largely depend on them. And if omnivores are fewer in number, the number of herbivores increases as there will be no predator for them.
The whole food chain will get disturbed.
Eg. Grass-> Grasshopper-> Rabit-> Snake -> eagle
Eg. Producers-> Herbivores-> omnivores-> carnivores
