A bird species is introduced in an area. The bird species feeds on the same seeds as the bird species that already occupied the area. What is the most likely effect on the original bird species?

Question

A.
The population of the original bird species will increase.
B.
The population of the original bird species will decline to zero.
C.
The population of the original bird species will decrease.
D.
The population of the original bird species will remain the same.

Answer 1

C. The population of the original bird species will decrease.

This is because the introduction of a new bird species that feeds on the same seeds will create competition for resources. This competition will likely lead to a decrease in the availability of food for the original bird species, ultimately resulting in a decrease in their population size.
