What is herbivores in the Manitoba deserts?
Manitoba has no true deserts.
Herbivores eat whatever grows, which is mostly succulent plants like cacti. Carnivores prey on the herbivores. The major difference between food access in deserts and other places is the timing of the hunt/forage: most animals are not active during the heat of the day or the cold of the night - dawn and dusk are when animals are typically active.
