Two warbler species feed on insects in spruce trees. Researchers measured the percent of foraging time at five vertical zones from canopy top to base.
The data best illustrate which ecological concept?
- Acheck_circle
Resource partitioning that reduces interspecific competition
- B
Mutualism between the two warblers
- C
Predator-prey cycling
- D
Founder effect in a small population
Explanation
Two species using different vertical zones of the same tree minimize direct competition for food, a classic example of resource partitioning (cf. MacArthur's warblers).
