How many carnivores are present?

There are more than 270 species that are carnivores. Carnivores can feed on herbivores, omnivores, and even other carnivores in an ecosystem. The carnivores in an ecosystem feeds/devours (on) flesh. A carnivore is able to eat another carnivore since they are also meat. On the other hand, The Omnivores in an ecosystemare more advantageous because their diet is the most diverse, and there is alot of variety. For example, an omnivore; a bear can eat grass, and even meat (they can also eat insects)

i think that it is c, d, and e, hope this
