To determine which animal's absence would have the greatest negative effect on the ecosystem, let's analyze the relationships:
1. **Rabbits → Foxes/Wolves**: If rabbits are absent, both foxes and wolves would have a food source missing, which could lead to a decline in their populations. However, wolves also have deer as an alternative food source.
2. **Deer → Wolves**: The absence of deer would primarily impact the wolves since they depend on deer as a food source. Foxes are not dependent on deer, as they primarily eat rabbits.
3. **Foxes → Wolves**: If foxes are absent, wolves can still find food from rabbits and deer. Wolves are at the top of the predator hierarchy in this relationship.
Since wolves are apex predators with multiple food sources (rabbits and deer), their absence would likely have the most severe negative impact on the ecosystem, as it would lead to an overpopulation of foxes and possibly rabbits (if they were able to breed unchecked).
In summary, we can conclude that the absence of **wolves** would have the greatest negative effect on the ecosystem, disrupting the balance of all the species involved and leading to potential overpopulation of prey and other predators.
