Question

If feeding efficiency of one species is reduced due to another species in the presence of abundant resources, it is called

• A. resource partitioning
• B. competitive release
• C. interference competition
• D. competitive exclusion

Answer 1

The correct option is C interference competition

Interference competition: In interference competition, the feeding efficiency of one species might be reduced due to the interfering and inhibitory presence of the other species, even if resources such as food and space are abundant.

Resource partitioning: If two species compete for the same resource, they could avoid competition by choosing, for instance, different times for feeding or different foraging patterns.

Competitive release: A species, whose distribution is restricted to a small geographical area because of the presence of a competitively superior species, is found to expand its distributional range dramatically when the competing species is experimentally removed.

Compeitive exclusion: Two closely related species competing for the same resources cannot co-exist indefinitely and the competitively inferior one will be eliminated eventually.
