In the context of interspecific competition, which of the following statements best describes the mechanism of "resource partitioning"?
Options
- ACompeting species avoid direct competition by choosing different feeding times or distinct foraging patterns.
- BA competitively superior species restricts the geographical distribution of an inferior species to a smaller a
- CThe feeding efficiency of one species is reduced due to the interfering and inhibitory presence of another spe
- DCompeting species evolve significant morphological differences to utilize entirely different ecological niches
Correct answer
A. Competing species avoid direct competition by choosing different feeding times or distinct foraging patterns.
Step-by-step solution
Resource partitioning is a mechanism that promotes co-existence rather than competitive exclusion. If two species compete for the same resource, they can avoid competition by choosing different times for feeding or different foraging patterns (e.g., MacArthur's warblers). Option 2 describes competitive release, where a species expands its distribution when the superior competitor is removed. Option 3 describes interference competition, where the presence of one species reduces the feeding efficiency of another even
