Wild animals like tiger, wolf, lion and leopard do not eat plants

Wild animals like tiger, wolf, lion and leopard do not eat plants. Does this mean that they can survive without plants? Can you provide a suitable explanation?

Answer:
It is true that these animals do not eat plants. They hunt and eat herbivorous animals like deer, gaur, bison, zebra, giraffe, etc. which are dependent on plants for food. If there are no plants, herbivorous animals will not survive and in that case animals like tiger, wolf, lion and leopard will have nothing to eat.
