Answer:
The fungi has a saprophytic relationship with the deer
The wolf has a predatory relationship with the deer
Step-by-step explanation:
A saprophytic relationship is the relationship where one organism feeds on the dead body/carcass/decaying organic matter of another organism.
This is the type of relationship that exists between the dead deer and the fungi because the fungus can only feed on the decaying carcass and not on the deer when it is still alive.
A predatory relationship is one that exists between two animals or organisms in which one hunts down the other and kills it for food. In this type of relationship, only the predator benefits, the prey doesn't benefit, he is food for the predator.
This is the type of relationship that exists between the deer and wolf. The wolf sees the deer as food, hunts it down and kills it.
The difference between both types of relationship is that the fungi feeds on an already dead organism while the wolf hunts down the deer before killing and eating it for food.
