Imagine that an ecosystem contains rabbits, foxes, wolves, and deer. The following predator-prey relationships exist:

Rabbits are eaten by foxes and wolves
Deer are eaten by wolves
Foxes are eaten by wolves

In this ecosystem, the predator-prey relationships are as follows:

1. Rabbits are preyed upon by both foxes and wolves. This means that foxes and wolves hunt and feed on rabbits as a source of food. Both predators target rabbits to sustain themselves.

2. Deer are preyed upon by wolves. This signifies that wolves hunt and consume deer as a primary food source. Wolves rely on deer for their survival and energy needs.

3. Foxes are preyed upon by wolves. This relationship implies that wolves feed on foxes. Wolves see foxes as a potential food source and will hunt and consume them when given the opportunity.

These predator-prey relationships illustrate the complex dynamics of an ecosystem, where different species depend on each other for survival. The rabbits, deer, and foxes serve as crucial food sources for the wolves, which play a significant role as apex predators, maintaining a balance within the ecosystem.
