Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In North American forests, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects found near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by-
A
allowing the birds to avoid many types of predators
B
reducing competition between the birds for resources
C
preventing the birds from interbreeding with each other
D
establishing dominance between the birds for nesting sites
Explanation: 

Detailed explanation-1: -Answer: 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.

Detailed explanation-2: -Which of these best demonstrates mutualism between certain types of bacteria and humans? Intestinal bacteria obtain nutrients from the gut and produce vitamin K used by humans.

Detailed explanation-3: -AI Recommended Answer: 1. Selective pressure most likely resulted in the development of the aye-aye lemur’s special adaptation when limited availability of water led to competition for mates and larger numbers of natural predators.

Detailed explanation-4: -What effect does continual mowing have on the ecology of the field? A Mowing increases the likelihood of nonnative species displacing native species.
