In the animal kingdom, all organisms are dependent on each other for food and this can be either represented in a food chain which is linear and is only a straight line from start to end or a food web which has many variables or food chains and different routes that could be taken from the producer to the tertiary consumer. The stomach has digestive enzymes that absorb the necessary nutrients. Foxes are quick, skillful hunters and can easily catch a dodging rabbit.
