The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.
