Two populations of birds in the same ecosystem begin to compete for the same food resources. what will most likely be the result of this interspecific competition? a. there will be a reduction in the population size of one or both species. b. there will be an increase in the population size of one or both species. c. one or both species will emigrate to a new ecosystem. d. one or both species will stop utilizing the shared food resources.

 A. There will be a reduction in the population size of one or both species.

Explanation:

Interspecific competition is an ecological competition which occurs between two distinct species which compete for the same type of resource. According to the competitive exclusion principle, no two species can have the same  ecological niche. The species which is more stronger and superior over the other receives the resources over the other. The other species will decline in number.

According to the given situation if the populations of birds in the same ecosystem begin to compete for the same food resource. There will be a reduction in the population size of one or both species due to the competitive exclusion principle.

the answer is d. chordata
