Question #46624
The Question
In the context of population growth models and interspecific interactions, which of the following statements regarding competition and resource partitioning is INCORRECT?
Options
- A.
Gause's Competitive Exclusion Principle is strictly applicable only when the competing resources are limiting.
- B.
MacArthur's warblers achieved coexistence by expanding their fundamental niches to utilize entirely new resources in the canopy.
- C.
Resource partitioning acts as a biological buffer that narrows the realized niche of competing species, thereby reducing the death rate caused by competition.
- D.
By spatially or temporally segregating foraging activities, competing species effectively prevent their combined population density (N) from prematurely exhausting the environmental carrying capacity (K).

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: The distinction between Fundamental Niche (theoretical physiological limit) and Realized Niche (actual ecological role under competitive pressure).
Students often assume adaptation to competition means 'expanding' capabilities, whereas resource partitioning is actually a 'narrowing' or 'specialization' of the realized niche to avoid overlap.
