This is known as the competitive exclusion principle. The competitive exclusion principle. Example: If the maximum population of a forest is that of carnivores, there will always be less availability of food in that area. Resource partitioning is usually expressed in predators like sharks by way of competitive exclusion, which means the conflicting species simply don’t occur in the same place all that often. 2.
