Question

Warblers feeding on similar foods in the same trees have demonstrated

A. allopatry

B. symbiosis

C. intense competition between species

D. resource partitioning

Competition

A. is a type of symbiotic relationship

B. always negatively effects both competing species

C. is also referred to as commensalism

D. has the same outcome as a parasite-host relationship

Answer 1

Ans) The correct option is "D" i.e resource partitioning

(It has been found that instead of competing among themselves for the same food or resource, the warblers will share the niche so that they can coexist in the same environment without eliminating one another).

Ans) The correct answer is "B" i.e always negatively affects both competing species

(In the interference or direct competition, two species will come into direct contact with each other for fighting to exploit the resources. And , in the exploitation or indirect competition, one species will try to exploit the resource more as compared to another competing species.

Competition is not a commensalism because in commensalism one species gets the benefit while the other species is neither harmed nor gets the benefit. Thus, it cannot be symbiotic relationship too because they are not dependent on one another.
