Final answer:
The correct food web model shows a predator like a fox above its prey, a rabbit because arrows in a food web indicate the direction of energy flow from the eaten to the eater.
Step-by-step explanation:
The model that presents a species relationship as it would typically be drawn within a food web is the Vertical model. From top to bottom, you would have a predator such as a fox, shown with a down arrow to a prey species such as a rabbit. This is because, in a food web, arrows represent the flow of energy from the organism being eaten to the organism that does the eating. Therefore, the correct sequence within a food web is the second option: Vertical model. From top to bottom: an oval with the label fox, a down arrow, an oval with the label rabbit.
