The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that:
Population A produced more offspring than population B
Population A consumed the members of population B
Both plant populations in this habitat decreased
Population B competed more successfully for food than population A
Competitive Exclusion Principle -
Two closely related species competing for the same resources cannot co-exist indefinitely and the competitively inferior one will be eliminated eventually.
- wherein
This may be true if resources are limiting, but not otherwise.
